If there is life on
Mars, it's not so far-fetched to believe that the Martian life may have in common
genetic roots of life on Earth. More
than 3.5 billion years ago, a lot of space meteors ricocheted around the solar
system, passing the same between the two young planets. This galactic game of
ping-pong left its traces on the Earth and on Mars, maybe then creates a common
genetic foundation between the two planets.
