Why must the proof exist? I have the power to make a snowman in the front yard. No such snowman exists. My reason for not making one is my own, but my kids will gladly make a poor attempt at one and tell their friends that I built it with one arm or something.

Am I my kids' imaginary father?

Blah blah blah milkman blah blah blah roto-rooter blah blah blah hilarious.

Seriously though, it is not trivial to prove that this "God" character exists. Too much of it (maybe all of it?) is cleverly built to require faith. Too clever for humans, maybe that's the proof? Maybe not, I don't know. I believe. I'm open to be proven wrong.

New cleaner gasoline will disable your hybrid car's battery, so you can't use it. Stick to the old dirty gasoline (until there are fewer and fewer stations that sell that type...)

Remember Turok 2? Gawd.
