Theland, your "first cause" argument doesn't wash, when you then claim an eternal spirit has always existed, with no cause and then made an entire universe out of nothing.
Neither does your claim, that if somebody can't 100% prove that evolution works, and how... that the only other solution must be a god.
You seem to persist with this idea that all atheists believe the same, and follow and believe other atheists. All it actually is, is not having a belief in the current religious offerings...
You have chosen to believe one, because you want to. But that isn't proof. If it was, there would be no agnostics or atheists left.
