Why the universe allowed Life to exist on Earth

Around 13.8 billion years ago, the big bang occurred allowing the universe to come into existence. After the big bang, galaxies, stars, planets, black holes, and other cosmic bodies began to form. Astronomers believed that our milky way galaxy was formed around 13.8 billion years ago. To put that into perspective, this is approximately 200 million years after the big bang. Many other young galactic worlds emerged and began to spread across the universe.

Within each galaxy, stars, planets, moons, black holes, and other objects also began to form and spread out with time. During the early phase of our home galaxy, many fascinating space worlds came into existence. However, our solar system was not in existence until billions of later.

Astronomers revealed that the solar system was formed around 4.6 billion years ago from an interstellar dense cloud of gas and dust. This implies that the Sun was formed 9.2 billion years after the big bang. After the formation of the sun, Earth and other planets slowly formed from the remaining nebula materials of the sun. However, in the early phase of these planets, scientists revealed that no form of life known to mankind could have emerged then. With time, Mars and Earth slowly developed habitable environments to sustain some form of lifeforms.

Astronomers revealed that Early Mars has a dense atmosphere that is similar to that of earth. With the red planet’s close resemblance to Earth, scientists assume that some form of lifeforms may have survived and thrived on Early Mars. But after Mars lost its atmosphere around 500 million years after its formation, its surface water dried off. Studies strongly prove that solar winds must have taken away Mars’ dense atmosphere, making its surface completely uninhabitable for any living species. Since Mars has lost its ability to sustain life, the Universe has to preserve the earth, especially our life.

How the Universe made life possible on Earth

Scientists have come up with numerous theories to prove how life came to earth. But most scientists are coming to believe the panspermia theory first proposed by the Greek philosopher Anaxagoras in the 5th Century BCE. The Panspermia theory has it that life actually originated in space, in most spatial ices which have continuously spread to the planets by comets and meteorites. Going by this theory, you will realize that the universe must have transported life to Earth from distanced space worlds.

Scientific studies conducted so far have revealed that the earliest lifeforms on earth were microscopic organisms (microbes) that left their footprints in 3.7 billion years old rock samples. This implies that microbes actually reached Earth billions of years ago and slowly evolved into creatures that grace this planet today. However, no life could have survived on Earth if the solar wind stole our atmosphere as it did on Mars. The universe made our atmosphere to be so thick that it holds back the most powerful radiations from reaching the earth’s surface.

Earth is surrounded by the Van Allen Belt which helps in trapping energetic electrons and protons to keep Earthlings safe from dangers of the outer space. Despite all these features, the Universe allowed the earth to form at the goldilocks zone of its star. In this region, the presence of liquid water made it possible to exist on Earth’s surface. Scientific studies reveal that most living species lived inside the ocean for billions of years. But around 530 million years ago, some earthlings left the ocean and became land dwellers. Over the years, they began to evolve and form different species. But all these while, the human species were yet to emerge from its ancestors.

Why the Universe Enabled Humans to Exist

After the land dwellers began to spread across the Earth around 530 million years ago, the human species were not in existence. But evolution played its role and the first human ancestors emerged around 2 to 5 million years ago. However, the homo sapiens, which are classified as modern-looking humans emerged around 200,000 to 300,000 years ago. For thousands of years, humans advanced and invented technologies that changed the world.

The universe allowed over 8.7 million species to exist on Earth. But humans are the most intelligent species to ever walk on this planet. We were so brilliant that we invented technologies that make life become much easier for us and to change the world. However, some of our creativity and inventions are affecting nature and exposing a once peaceful planet to global warming. But we are heading towards the future where we will correct our past mistakes and focus on using our intelligence to do the proper work which the universe has mandated us to do.

You may be wondering what job the universe has for humanity. The Cosmos in its early phase began to spread light across its platform. The Universe allowing life to exist on Earth implies that it wants us to spread the light of consciousness to deserted space worlds like Mars, Europa, and Titan and even extend to Interstellar space. Despite our level of technology, we are yet to discover another form of lifeform. Maybe, the Universe is hiding other civilizations away from us to inspire us towards spreading life across any reachable space world.

Are we living to fulfill this goal? The answer is YES. We formed the space program with the goal of reaching new space worlds. NASA has successfully sent humans to the moon, and the American space agencies alongside other agencies are targeting a crewed mission to Mars. One thing is certain, human civilization will continue to thrive until it spread the light of consciousness across the cosmos.

Conclusion

The universe allowed life to exist on Earth for a living. The good news is that we already have space programs and are prepared to send humans to distant space worlds to unveil more facts about the universe. NASA’s James Webb space telescope is currently looking deep into the Cosmos to unlock more fascinating mysteries for mankind. With the effort made so far, humanity will surely thrive and break new limits with future space technologies. What are your thoughts about the existence of life on Earth?

  1. Here’s the funny on this one fact . We are not alone. Throughout the history our civilization has and continues to have visitors. I’m not one of those alien hunters but the truth behind this came from an interview with Richard Pryor and an archeologist. This was a path that was covered by Egypt… I prefer to never call the thief’s that btw. When we ourselves can even phantom how the Pyramids were built and this area was an oasis and many species that can kill you in under a minute and our lifespan ment we were pushing up daisies by our 40s if we were the lucky ones
    Mathematics is the life of the universe and if done correctly , the one will equal many . Time is and always be a human factor and the funny part about that is , we also come with an expiry date. Can you imagine that time didn’t exist ? No , but for another infinite is a child’s game . We are not the center of the universe and that’s the absolute fact . We are just a single solar system sitting on the edge of the Milky Way and just to give you how massive it really is , pick up a grain of sand and consider that to be our solar system then look to all the deserts and beaches which alone is our Milky Way. Life as our sun brings life so shall it be
