To be honest I suspect that evidence is pretty far down the list of priorities for both Atheists and Theists alike. I imagine that the topic of evidence comes up so much because it gives both sides an illusion of having been established rationally. I would argue that it seems people are more or less predisposed towards Theism or Atheism and that relatively few people arrive at their position as a result of analyzing the evidence before them.
I've argued in the past that if evidence really was all that mattered then all Atheists would become Pantheists or otherwise adopt a form of Theism based on the observable material world. Similarly it seems that no amount of evidence to the contrary can shake some Theists from their particular perception of god/s.
What evidence do you think supports pantheism?
