My answer would be the same as Stephen Fry's

I never asked to be created

How dare you judge me for being exactly the way you created me

Playing along here, I like your demand, but I'd first want to know 'Whose God are you? What description that we have is the closest match? I mean, somebody's gotta be right about you, right?' And then, considering the issue of divine hiddenness, I'd want to know, 'Where the hell have you been all this time?' But one thing I would never do is bow my head or kneel.

God would have some shit to answer for...

I would tell him I'm not impressed.

Why would an omnipotent and omniscient god care? If I live life right and make good decisions for people around me and the greater good, he/she/they ought to be rather satisfied with the results. If not, then I'm owed an explanation.

I don’t worry about that kind of stuff as it just impossible.

Does the pot of gold make you more likely to believe in Leprechauns? No, promises of rewards and punishments that are only delivered after we die are meaningless without a way to verify.

No, really, what's up with the platypus?

Using my best SNL Chris Farley "Do you remember" impression, I'd say: Do you remember that time when you drowned everyone because you were mad........ That was awesome.

If god wanted people to believe it'd give us evidence.

I'd say "tell me about yourself!" Because all I've heard from the religious has been ridiculous.

Go, 'damn yourself'.

Yes but what if he said "I just created you and gave you free will to do as you please. You created religion all on your own. "

I'd spit in it's eye, and take a swing at it for being such a passive/aggressive douchebag.

You should’ve talked to us. Really. Don’t expect to be believedwhen you communicate in such a cryptic manner.

Not only "apologize", but explain. Explain things like disease, famine, allowing people like Hitler, Stalin, Dahmer, and the Conquistadors. I would also ask him why give us something as precious as dogs, and then take them away after only a few years? Why let complete assholes live, while killing good people? Basically, explain his amazing plan so that it makes sense, and explains the evidence (including his inconsistencies, hypocrisy, and the judgment of his creation).

Also, I would want to know if we were just one of his many "experiments", given the vastness and age of the known universe, and why he chose some of the odd methods he did for "making himself known" as the One True God.

"Even if your God WERE real, I would not worship it."

IF he existed, and everything was true, why would he owe you an apology?

What bands do u like i love music and make it i se u lovecmetal like me

I kinda love this group of people.

I'd say, "So Sam and Dean Winchester were right about you..."

If that is what the truth is. god knows what is going to happen so what's the point?

You've got a lot to answer for, there, Bub.
