If he did present some "evidence", would you objectively examine and consider it?
The problem with people who call for "undeniable proof and evidence", really don't want it to begin with. What they really want to do is cover up their own insecurities and lack of evidence to the contrary by unfairly keeping the burden of proof on the believer. They already think they've "won" anyway, so they have no evidence and don't feel they need it.
If someone believes flying unicorns existed, so what? That's on them.
But if YOU'RE going to assert God doesn't exist, you have no burden? This isn't table shifting,... you do have some burden to prove that what we believe is hogwash.
The world doesn't work that way. What you can't do is assert you're right without proving it either.
If you can't meet any of your criteria to prove he doesn't exist (which I am assuming is the position you hold), you need to live and let live, and give believers the same respect you want. Keep your non-believe to yourself, everyone doesn't care to hear it either, just as you don't care for what believers have to say on the matter and should keep it "personal".
