just a theory

well we all know about the hurricane on mars, which happens to be giant. With extreme winds, a perfectly unihabitable place to live. Call me crazy but that would be the best place to have a civilization. See it appears uninhabitable, big vast amounts of living space, plus you have the benefit of never being bothered. Now it may seem crazy but it is possible

I donnu maybe if they live underground as I have seen people kinda point to. However me myself and I need a good tree to look at every now and again. Also the calm of snow falling I would never give that up. Thats just me

With what you said I am curious about the numerous claims about the moon as well. There is never anyway we can research beyond telescopes and nasa photos which sucks :Z
