Scientists have found evidence that the fact that the planet Theia is the size of Mars crashed into earth, initiating life and creating a moon is real.
In an article just published in the scientific journal Nature Ecology and Evolution, a group of scientists from the University of Bristol (UK) said that life on earth originated 100 million years earlier than we thought it was 3.9 billion years ago instead of 3.8 billion years like some previous studies.

To find Earth’s oldest common ancestor, the team of scientists used molecular data from 29 genes from 102 different species of living organisms, refined with data from nine fossils to find them. the first unicellular organism.
The results showed that this first organism was born about 3.9 billion years ago after the embryonic process of hundreds of millions of years from the earth. The oldest fossils on Earth are 3.4 million year old microorganisms that have just been discovered in Western Australia. But before that, there are signs of carbon dating to 4.1 billion years ago. Pristine carbon is known as the starting material for “essentials for life,” as NASA discovered at the bottom of a 3 billion year old lake on Mars.

The team claims that the chain of miraculous reactions to the first embryonic earth stems from a horrific planetary collision: “hypothetical planet” Theia is real. Theia the size of Mars was plunged directly into Earth 4.45 billion years ago.
Theia collapsed, its materials merged into the earth and changed our planet forever. Much debris from the impact moved up Earth’s orbit, forming a giant rocky cloud. This cloud then calmed down and gathered to form the moon. This is why the analysis of the lunar rock shows that it shares the same materials as the earth. Theia in Greek mythology was the titan who gave birth to the moon goddess Selene.

In The Conversation article, Holly Betts, a graduate student in paleontology at the University of Bristol and a member of the team, said she would continue to refine the results as people find more. Other ancient fossil evidence.
They hope this study will shed more light on an early historical period with many mysteries.
