I have the conclusive proof he does not exist: there is absolutely no evidence found throughout history to back you up, all you have to back up your theory is what is in your head and what is written in a novel...and that just aint good enough for me.
Where did I tell you god exists? Please, if you're going to act all offended, at least get your facts straight.
As an extra, you do not have proof god does not exist. Absence of evidence is not evidence of absence.
you can not ask someone to prove something is, when there is nothing to prove in the first place and nothing to prove it with!
I honestly have no idea what that last sentence is meant to be about. On the off chance that it's the usual 'you can't ask someone to prove something doesn't exist' then that's outright wrong. The only way you can say something is definitely the case is to disprove all other possibilities.
