My opinion that there is no god at this stage in life is a fact, you prove to me there is a god and I will change my opinion, the ball is in your court.
Sorry, but that's not how it works, psychoslice.
YOU made the claim that it is a fact that there is 'no god at this stage in life." It's your claim, and your responsibility to prove it.
After all, I made no claim that there is one...and certainly didn't have the chutzpah to claim that His existence is a FACT.
According to the dictionaries, "fact" is defined as "something that truly exists, or happens. Something that has actual existence."
Not 'belief or opinion about the existence of something." My own personal opinion that there is a God, no matter how deep and sincerely held--and I do deeply believe that He does exist, btw-- does not make God a 'fact.' He either is, or He is not, whatever I think. Indeed, any fact is a fact no matter what people think, it's true, unless you start messing with the folks who like to do thought experiments with imaginary cats in imaginary boxes.
Your problem, though, is that you are not only claiming that your opinion that God does not exist means that God's non-existence is indeed a FACT, (which puts you in the unenviable position of having to prove a negative), you are also committing the logical fallacy of reversing the burden of proof, as well as setting up a false dichotomy. It IS your job to prove your own claim, and if I cannot prove that my beliefs about God are true (and y'know what? I can't), that doesn't automatically mean that there is no God at all. It's not an 'either/or' thing here, sir.
If MY beliefs in God aren't true, why...someone else's ideas about God could be. Or God could exist in a manner no human has thought up yet.
.......................or not at all.

The point is, sir, your claim, your responsibility to prove it, and you need to be a bit more careful about how you throw words like 'fact' around.
