While it's true that the solar wind has blasted most of Mars' atmosphere into outer space, it is also true that Mars' gravity has kept some of it in place.

Results- Mars does not presently have a global magnetic field but had one early in its life, similar to that of Earth. .

Considering realities like
Deinococcus radiodurans there may indeed be microscopic life on Mars, but I'd doubt it because what else but said bacteria could survive in the first place? Are you suggesting a thriving ecosystem solely of radiation resistant bacterias? Is that what we are hoping to find? Wonderful, hundreds of BILLIONS of dollars well spent then I suppose

would you eat your shoe like werner herzog if they find bacteria on mars?

Its not dogma silly, its science like Bill Nye yo! What NASA is looking for on Mars is not necessarily evidence of existing life, but rather, evidence of previously existing life. Further, that is really only secondary, the primary objective of the past missions and rovers is basic geology
Geology is fun, but is it worth such funding? Again, I am not against NASA in general, just spending shitloads of monies on intellectual curiosities meanwhile people around the world and even in our own country are quite literally starving to death or dying of preventable diseases..
Priorities people!
