I’d be surprised if there wasn’t. Surface conditions were amenable to it in the past and there is doubtless viable conditions in the subsurface for microbial life to survive.
Hogwash.
There are undoubtedly microbes there now, since we landed our contaminated hardware there.
But otherwise there would be no purpose for life to be on mars.
Agree. It seems something caused some big changes to occur in the past. Some images clearly indicate significant amounts of water once existed.
Hogwash dittos.
I too believe life is probably on Mars. We know now there is liquid water at the surface in intermittent seeps, there is still heat in the core of the planet, it is close enough to earth for life to make the leap in the form of earth meteorites, and life is probably a natural, if rare form of matter. All matter self-arranges into patterns, such as crystals, and life is just an extreme example of that.
