Ah, but don't you see. The lack of evidence is proof that there is a supreme being, because any being that was less than supreme would, even if only accidentally, leave evidence. Since there is none at all, that is something that only a supreme being can do.
Some people see the lack of evidence as evidence that there is no supreme being. That's like saying conspiracy theories are proof that there are no conspiracy theories. Let the obvious be obvious and stop trying to second guess our illustrious, inevident supreme being, who is way too busy being anonymous to have time to reveal himself anyway.
Oh, and some of us have superpowers (myself included) but none us are so frickin' insecure that we feel a need to run at the speed of light or see through clothing or nonchalantly toss army tanks over our green shoulders. Let alone fire lasers out of our eyes. That's the sort of thing only authors of fictional comic books make up, and that's because they don't have superpowers and they're just guessing how they would be used. And they're way wrong.
But go ahead and be an atheist. It is all part of his master plan, which includes instilling doubt in a large enough percentage of the population that it causes true believers to think (or at least try to think) and then to draw their own faulty conclusions about his existence, which promotes both inept customization of religions and infighting amongst the loyals. Because what fun is it to be a supreme being if lots of people don't die because of you? I mean, a few folks with superpowers are no justification for using ones supreme abilities. Dead people, on the other hand, make the whole endeavor worthwhile.
What better way to know that you're a supreme being than being able to watch folks die fighting over you. And no, that's not ego tripping. Supreme beings don't have egos. Well, at least the one I've never seen doesn't.
