life on mars  once we introduce bacteria to mars cant it survive forever there? i looked it up and they said they purposefully wash down the rockets so no organic matter makes it there. i mean what the point of that if we hope to one day colonize mars? once bacteria is introduced life will evolve on mars itself even if humanity fails and goes extinct shouldnt we just introduce lifeforms that can survive there. i dont know what theyd be but there has to be something that can survive there.
