Life in the solar system may have first originated on Mars, not Earth

 A new study published in the journal Science Advances suggests that the organic molecules that allowed life to begin were present on Mars about 4.5 billion years ago.

And while these critical components may have hit Earth around the same time, it was on the Red Planet that life found its most favorable conditions.

Earth and Mars are members of the inner solar system, made up of four rocky planets and an asteroid belt. Shortly after their formation, these terrestrial planets were brutally bombarded when a shower of asteroids hit the inner solar system.

While these rocks were assimilated into the crust of Earth and Mars, the movement of plate tectonics on our home world caused these ancient meteors to fall into the interior of the planet.

In contrast, the surface of Mars is stationary, meaning that rocks that crashed into the planet in the distant past remain in place and can be studied....<<<Read More>>>...
