> Atheism is just as unprovable as theism.
Perhaps, but what matters is that it asserts less than theism. When you start from no evidence, you need to believe in as little as possible until enough evidence presents itself that you can change your mind.
This is especially true given that religion has a highly plausible explanation as man-made, a creation of human imagination. When you have a collection of assertions, with no evidence, and the only physical source is the human mind itself, why would you believe it has any correspondence with reality?

I never disputed this.
> To believe that this is impossible and that we're capable of observing/measuring every part of reality is hubris.
I feel like you have created a strawman, because I never used any of these arguments.
Yes, of course we don't know every happening in the universe. Yes, our senses and reasoning skills are limited. That doesn't make religion true. How could it? Religious people have the same senses, the same access to knowledge as everyone else. I don't believe that religious people have any insight into the workings of the universe that no one else does, especially given that there are so many religions that can't agree with each other about even basic tenets. It's a very human creation - not a truth of the universe.
But I'll never assert that theism is impossible. That wouldn't be defensible, because we don't have all the information in the universe (or outside it!). Of course it's possible, but that doesn't matter, because we have no evidence whatsoever to believe it.
