Benner says minerals containing the elements boron and an oxidized form of molybdenum were central to the process -- but at the time, Earth was probably incapable of supporting enough of such minerals. He tells Space.com that analysis of a Martian meteorite revealed the presence of boron on Mars, and "we now believe that the oxidized form of molybdenum was there, too." As such, "the evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock," says Benner. "It's lucky that we ended up here, nevertheless -- as certainly Earth has been the better of the two planets for sustaining life."
