Even better -- these are potentially fertile Petri dishes, well within the
reach of crosscontamination through impact ejecta. I would find it entirely
unsurprising if any world with liquid water (once, on surface, now
potentially trapped deep below) would seethe with primitive life. That life
and us having a common origin.

Yes, it's hard to see how prebiotic Mars would have avoided being
contaminated by Earth. Or, vice versa. The Oort and Kuiper clouds must have
prefectly preserved evidence of these early impacts.
