What are you on about? Atheism is rejecting a ridiculous belief system.
Y'all are arguing the same thing with these two sentences.
There is nothing for atheists to prove, they made no claims. Religion is the one making claims, so it's on them to prove it. Atheism simply says "no thanks, the evidence you provide is insufficient and I don't believe you".
That sounds like trying to disprove a negative to me. Just because it's an absurd negative doesn't mean it's not impossible to disprove it.
I don't want to get into all the nitty gritty, but the weight against the big sky person is "we definitely don't see it." and the argument for the big sky person is "we definitely feel it."
Y'all are both spending a lot of time arguing about the big sky person regardless of your stance.
*edit
actually, i just saw this comment, and i'm not gonna argue with that.
