I would presume it's chemical composition, huh? While many dispute
the evidence of life, no one, to my knowledge, is disputing that it's
a piece of Mars.
It's not hard to imagine that an impact w/ an asteroid would be able to
accelerate a piece of the planet to escape velocity, is it?
If there was bacterial life on Mars 4 billion years ago, how does that
compare to the beginnings of life on Earth? About the same?
