Hmm... so, everybody, what ideas would you have a terrible time accepting? It would take a heck of a proof to convince me of any of the following:

1) The existance of a god or gods. There's no evidence for or against, but as far as I can tell, the universe writes its own rules without needing help from a god. On a deeper level, though, I just don't like the idea of a 'higher force.' If it's all part of some god's plan, then free will is in the toilet. I don't want anybody in control of my life except me.

2) That there is life in the solar system (native or visiting) anywhere but on Earth. I do feel that this is ridiculously unlikely on scientific grounds, but I'm more attatched to the idea than that. Perhaps because I think life somewhere else in the solar system makes life on Earth less special. That might be hypocritical coming from an atheist. I'm not sure.

3) That we will ever find an 'ultimate theory' of the universe. I can't think of any rational basis for this one at all. I guess I just don't like the idea that we can find ourselves with nothing left to discover.
