You're right. You can dispute. But when it's placed right in front of you, the dispute is instantly null and void.
In a sense, you're right here as well. Again, though, the lack of evidence to prove God's existence becomes the proof of (a probable) non-existence. I don't have to prove that He doesn't exist because there is no evidence to disprove it.
That we shall. Like I said before, I'm not a total non-believer. I'm one who just has lots of questions that will literally NEVER be answered by anyone on Earth. Later, QD.
