Who created Mars would be the next trick question...
Why would the source of life on Earth be different from the source of life on Mars?

The design space spans 'em both

If there is life on Mars, and IMHO there is probably at least some forms of microbial stuff, it probably originated on Earth. All it would take is one good comet impact on Earth to seed the inner half of the solar system.


Bugs are everywhere. They probably have roaches on Mars.
