Evidence for God

This is a fair point, but one that does not apply to this conversation. The one problem is that nature and we DO exist. The question isn't whether we believe in nature and us. The question is do we believe it was an accident or that it was intelligently designed?

A more appropriate way to put that argument you linked to would be to say:

I found this perfectly square diamond. Did nature just happen to make it that way? Did someone come and cut it into a perfect square? Or did "God" make it that way?

I think the most likely answer is that someone came along and cut it that way and left it behind. The problem is that you have to believe in aliens to use that answer for nature, the planet and all the perfectly designed DNA of creatures around us.

It actually applies perfectly to this conversation, as the OP posted a website supposedly "proving" gods existence. The proof contained within is little more than burnt fingers and eye witness stories. Along with it come the commentators that say they shouldn't have to supply proof as to why god exists and it is US that should have to supply proof as to why he DOESN'T exist. From Sagan's essay:

"Your inability to invalidate my hypothesis is not at all the same thing as proving it true. Claims that cannot be tested, assertions immune to disproof are veridically worthless, whatever value they may have in inspiring us or in exciting our sense of wonder."

That applies perfectly to the argument of god's existence.
