Are We the Martians? What if life didn’t originate on Earth, but on Mars—arriving here inside a space rock? The intriguing idea that life on Earth began on the Red Planet.

More likely Venus originally. It was earth like until its runaway greenhouse effect warmed it up like a microwave.

I would guess early life on Venus, they explored earth but settled the moon and mars until earth was more hospitable.

I’m high. Don’t judge my pontification on the origin of our species.
