isn't the burden of proof on believers?

Yes, it is. Because you can't prove a negative.

I'm sure one of the beauties of faith from the believers' perspectives, is that by definition, faith is belief without certain proof. No proof needed.

conservatards disagree :)

I seriously doubt this is an issue which falls along party lines. It's neither conservative nor liberal to have faith in a God that by the dictate of faith, chooses to keep itself hidden. It's a human need, imo.

i don't hear liberals denying science and insisting science is invalid when it fails to prove god exists. but i hear plenty of conservatives who do.
