What was the species of bacteria? Was it known or unknown prior?
Is the conclusion then that non-living substances in the rock combined to produce life?
Has that ever been duplicated in a laboratory?
Has any scientist witnessed non-living substances getting together to bring forth anything living?
I don’t think anyone concluded that nonliving rock spontaneously produced the bacteria.
I don’t think anybody has observed nonliving stuff produce living stuff. Remember way back when they thought garbage produced flies? I don’t remember his name but some scientist proved that wrong with a set of experiments.
My point was an aside, isn’t it amazing what turns up when you look in a new place! If we actually could peel a comet or asteroid apart, I bet we’d be surprised, amazed, and astounded at what we’d find there.
