The issue at hand over at Pharyngula is whether there could ever be any ‘proof’ for the existence of God that PZ Myers would find acceptable. PZ claims there could be no evidence that would change his belief in atheism. You can follow the link to find examples of people who both support and debate him over his unwavering stance.
It’s not the usual biblical nutcase vrs. reality debate most prominent on PZ’s site. It’s atheist vrs. atheist. You might find it interesting to see how intelligent people with differing views actually engage in reasonably discourse over such a contentious matter.
Enjoy.
