Early Earth
Earth first formed a long 4.6 billion years ago.When our dear Earth was young, life, would have been impossible. Lava spew over everywhere in every which way, turn Earth into a wasteland. There was no water, and the ground soaked in lava, with no place to hide from it.
When a layer of molten rock spread over the whole globe. As Earth continued to cool into solid rock, volcanos still bombarded the ground with bursts of lava. This continuous flow of lava released chemicals trapped deep inside earth, to create Earth’s atmosphere — though, the air at first was poisonous, making our world inhospitable.
Asteroids, comets, and small planets, played a huge role in cooling Earth. While Earth was a blistering wasteland, it was continuously hit by asteroids, comets, and brought Earth water.
How Oceans Formed
As Earth slowly cooled, (to a form which resembles more like right now than the “lava land”) so did the atmosphere. Steam released from volcanos condescended to a liquid form (water) which created a downpour that lasted for as long as a million years. Constant bombardment from comets and asteroids gave earth even more water.
The First Life
Most scientists think that life started in the deep sea, 3.8 billion years ago. The reason most people support that life started in the deep sea is that it was much safer than Earths surface. The first life forms may have lived around hot water, feeding of energy rich chemicals dissolved in the boiling water.
Mimicking Molecules
The first life was not an organism, nor a cell — it was just a molecule that was able to create copies of itself. This is what DNA does. Since DNA cannot copy itself other than cells, the first living molecule probably worked on something different than DNA.
Final Thought — The Beginning of Everything
From a burning world of fire and chaos to silent oceans hiding the first sparks of life, Earth’s story is one of transformation. What began as molten rock and toxic skies slowly shaped itself into a cradle for existence. And in the depths of those early oceans, a single self-copying molecule may have started it all — quietly, invisibly, but powerfully. Every living thing today, including us, traces back to that fragile beginning… a reminder that even in the harshest conditions, life finds a way.
