This seems like the better explanation of my laybrain reading this and thinking; why would you start with soil? If it were a true geological phenomenon then shouldn’t they use a sterile jar of granite dust or something that only existed on earth prior to life? It seems like pointing at a jar of bio matter and saying we can’t stop it is not really a good methodology to base much upon. I barely ever even took a chemistry class in my life but something just feels wrong with this approach to me. I assume that’s what the other scientists who doubt the sterilization were thinking too.
