You can't prove a negative (parody)

[CapnAwesome]

Yet it would not prove the universe exists. In fact, in philosophy, it's pretty much admitted, you can't prove physical world exists. It's a properly basic belief.

Well now we are just talking about degrees of certainty. Lets say I measure the radiation levels of the sun, I measure it's light waves, I measure the gravity effect it has on us. Can I say with absolute certainty that it exists? No. I could posit that it's a very complex hallucination or I'm in the Matrix, etc. However what's the evidence for either of those? Nothing. It's the same with God. That's why I think the argument is not absurd. Dealing with things in a strictly black and white 100% or 0% terms is the only way in which the argument can be made to look absurd. Since that's not the case, and things have various probabilities, it stands.
