It's only when you can see the miracle of life we inhabit, that internal conflict seems futile. We should all be working together.

Given man's propensity to wage war, and now with the ability to wipe humans from the face of the earth, you may be wondering if our precious blue planet will still be here in the next 100-200 years? With China and Russia on a path for a clash of the titans, and only the US and NATO standing between democratic freedom or communistic enslavement. The inevitable may be a total thermonuclear sterilization of the planet.

So far, we have survived two world wars, with a third world war looming like one of the mushroom clouds, the devastating signature of an atomic release.

All nations need to adhere to the notion of: "Law, Not War." Bury the hatchet and do their utmost to quash inappropriate leadership with dreams of global domination, tending to destabilize international relations.

The United Nations dreams of a world where tolerance and respect for ideals and beliefs, tempers itchy fingers on big red buttons. A legal framework to prevent annihilation. As it seems, dependent on restraining megalomaniacs, by voting in common sense. So, prosecutions of those willing to take the lives of political opponents, who would rule by fear.

This will be a tragedy, of biblical proportions, and an unthinkable loss of opportunity to share technology for the perpetuation of life itself. Granted that it is something of a miracle, billions of years in the making.

The phrase "extra terrestrial" (ET) originates from a combination of Latin words:

Extra: meaning "outside" or "beyond"
Terrestris: meaning "earthly" or "of or relating to Earth"

Therefore, "extra terrestrial" literally translates to "beyond Earth" and is used to describe anything that originates from outside our planet. This includes objects like meteoroids, asteroids, comets, and potentially, life forms existing on other planets or moons.

The Earth's life-supporting environment is a confluence of fortunate astronomical and geochemical circumstances that allowed for the formation and gradual evolution of complex life over billions of years.

Let's explore the unique characteristics of Earth's formation, its position in the solar system, and the ongoing planetary processes that all played a crucial role in creating a suitable habitat for life as we know it. Let's delve into the potential origins and the immense timescale required for the emergence of complex life forms on Earth.

ARGUMENTS TO SUPPORT THE A THESIS

We are fortunate to benefit from a favorable Stellar System. The Sun, a stable main sequence star, provides a consistent energy source for Earth in the form of light and heat. The Sun's relatively quiet nature, with minimal solar flares, minimizes radiation events that could have hampered early life. The ancient Egyptians worshiped the sun god Ra, by way of early recognition of their good fortune.

THE GOLDILOCKS ZONE

Earth's orbital distance from the Sun places it within the habitable zone, where liquid water, essential for life as we know it, can exist. We have an ideal stellar orbital zone.

PLANETARY COMPOSITION & GEOLOGICAL PROCESSES

Earth's size and composition provided the necessary conditions for life on earth to develop. A strong gravitational pull retained a dense atmosphere. The presence of essential elements like carbon, oxygen, hydrogen, and nitrogen - are the building blocks of life.

Plate tectonics continuously recycles elements, creating a dynamic environment conducive to life. A bit like tilling soil. Volcanic activity releases essential gases, contributing to the early atmosphere and potentially providing energy sources for early life forms.

FORMATION OF THE MOON

The Moon's gravitational influence is believed to have stabilized Earth's tilt, influencing climate patterns and potentially mitigating extreme weather events.

THE ORIGIN OF LIFE

The exact process remains a mystery, but theories suggest the formation of complex organic molecules in early Earth's oceans may have laid the groundwork for the first self-replicating entities. It is not beyond the realms of possibility, that these organic molecules were formed on other, maybe extinct planets, trillions of years ago.

TIMESCALE FOR COMPLEXITY

The development of complex life is a gradual process that took billions of years. Natural selection, random mutations, and environmental pressures over vast timescales played a crucial role in the evolution of diverse and complex organisms. The evidence for which is reinforced in the theories of Charles Darwin, though using only complex animal adaptation as his model.

The existence of life on Earth is a remarkable outcome of a confluence of astronomical and geochemical factors. Our planet resides in a nurturing environment within a stable solar system, possesses the necessary elements, and undergoes ongoing processes that have all contributed to the emergence and continuation of life. However, the transition from simple life forms to complex organisms required an immense period of time, highlighting the intricate and gradual nature of evolution.

RARE EARTH HYPOTHESIS - WHAT ARE THE ODDS OF FINDING ET?

The Rare Earth Hypothesis, suggests that the conditions necessary for life as we know it may be uncommon in the universe. In future explorations, the ongoing search for life elsewhere in the universe, it will be beneficial if we understand Earth's unique characteristics, as a guide this search.

The ongoing debate about the role of chance events versus deterministic processes in the origin and evolution of life, depends on your point of view, as a scientist or believer in a higher force, as the creator. Where, understandably, coming to terms with the scientific data requires a comprehensive grasp of the many facets of numerous strands of science, that is beyond many. And the goal of a very few.

The odds of finding another Earth-like planet with life existing at the same time as us might be slim, but the vastness of the universe makes it a possibility. The focus on finding planets with the right conditions and searching for bio-signatures might shed light on the existence of life beyond Earth in the coming years.


THE DRAKE EQUATION - FINDING EARTH LIKE PLANETS

The Drake Equation attempts to estimate the number of civilizations in the Milky Way galaxy that could potentially communicate with us. It includes factors like the rate of star formation, the fraction of stars with planets, and the fraction of planets that could support life. However, many of these values are highly uncertain.

The ongoing discovery of 'Exoplanets,' especially those within the habitable zone of their stars, suggests that Earth-like planets might be more common than previously thought. However, we still lack definitive information about their potential for life.

The are many Challenges in Estimating Odds, such as Limited Data. We only have one example of a life-supporting planet (Earth) to base our calculations on. Hence, the variables are uncertain. The specific conditions necessary for life's origin remain under debate.

POSSIBILITY OF MULTIPLE LIFE FORMS

While we know life on Earth is carbon-based, it's possible other elements could form the basis of life under different conditions, by way of chemical diversity. Scientists are exploring the possibility of life forms utilizing silicon or ammonia instead of carbon and water. The composition of the "primordial soup" on early planets could vary depending on the planet's formation and environment. This variation might lead to different prebiotic molecules and potentially diverse life forms.

The vast timeframe required for the emergence of complex life on Earth suggests it might be a rare phenomenon even on suitable planets. Even with a suitable environment, the necessary evolutionary steps for complex life might not occur on all planets.

In essence, the odds of finding another Earth-like planet with life existing at the same time as our existence, given the propensity to war and the technological ability for self destruction - are likely very low - considering the vastness of the universe and the immense timeframe involved. However, the discovery of numerous exoplanets and the potential for diverse life forms based on different chemistries suggest that life itself might be more widespread than previously thought.

FURTHER EXPLORATION

The James Webb Space Telescope is a powerful tool used to study exoplanet atmospheres, potentially revealing signs of habitability or even biosignatures – chemical signatures that could indicate life. The field of Astrobiology Research is constantly evolving, aiming to understand the origin and potential for life beyond Earth.

The search for life on other planets is an ongoing endeavor, and future discoveries may shed more light on the likelihood and diversity of life in the universe.

SPACE RACE - It's more of a crawl now, but when Russia put their Sputnik in orbit, the USA went into overdrive, trying to beat that achievement. That led to Man walking on the Moon, and the Space Shuttle. The new target is Mars. The Space Shuttle is launched into space with liquid hydrogen (LH2) and liquid oxygen (LOX) rocket motors. NASA developed the cryogenic tanks that may one day allow us to trade and transport LH2, the same way we trade and transport oil in tankers. Thank you NASA : )

STAR WARS - I am worried about China shooting at their redundant satellites with lasers, causing debris that is potentially dangerous to stations. Weapons in space. and weapons aimed at space. should be banned. Air Chief Marshal, Sir Mike Wigston is quoted as saying that Russia has deployed satellites that "we would describe as having the characteristic of a weapon and they practiced a maneuver, that we would say, could only have been done to deliberately destroy another satellite".

And China has continued to "develop anti-satellite technology, and that’s everything from missiles that directly target satellites, to laser dazzle weapons, to electronic jamming to physically ramming other satellites".  China has tested out the dangerous stunts against "their own redundant satellites" and proved successful, Sir Mike told The Telegraph.

Satellites provide communications, navigation, and intelligence to any nation's war machine, so knocking them out would seriously disrupt - and even render useless - much of its equipment. The Air Chief Marshal warned: "A future conflict may not start in space, but I’m in no doubt that it will come very quickly to space, and it may well be won or lost in space. July 2021

Alternative ways of visiting other worlds in person, might be cloning humans from frozen eggs, conditioning their brains and uploading memories, to recreate the scientists of today, again, for tomorrow. This theoretical concept is the basis for a fictional story in the rebirth of Cleopatra: Cleopatra's Mummy. In researching the technology to make the novel (film script) more believable, the subject of cloning and DNA manipulation, memory implants and synapse conditioning were all rehearsed and found to be science faction, not fiction.

The technology exists for deep space exploration, subject to development. Arguably far more reliable than the more common theme of Cryostasis (clathrate hydrates), the reversible cryopreservation of live biological objects, or Cryonics; the experimental process of freezing a person for later resuscitation to create a state of suspended animation, a common theme in science fiction.

The way we are treating planet earth, we could need a B planet sooner than space researchers think, to keep humans and other species on earth alive, as Planet A first dries up then floods. I wonder if they (World Bank, IMF, etc) should hit the reset button on printed money and stop the financial clock. That would reverse climate change via economic cooling. I wonder if printed money should once again be index linked to the real world. Today, this might be in relation to what planet earth can comfortably sustain. Unfortunately, not the perpetual growth most politicians thrive on.

Mars is the nearest potential planet for colonization, but is extremely inhospitable with no atmosphere to speak of, being 95% carbon dioxide.
