Did life on Earth start on Mars?

Are we all Martians?

An internationally renowned Geo-chemist caused a stir Thursday when he said, "the evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock."

Is this the stuff of science fiction? Or could there be truth to the theory?

    Maybe the same way we are exploring the universe to leave earth is the same way life got here before the other planet was destroyed, then had to start over to be where we are now.
