Here's an odd, theological sort of question for debate

[Answer]

Your particular religious beliefs are sort of irrelevant in this discussion - but I was speaking with my girlfriend earlier in regards to the evolution/creationism debate that's been going on recently, and she stated that she can't understand how people could believe in creationism - to which I replied something similar to "It's pretty much the same thing as you believing in Spirits and Ghosts"

and then I began to think about it. I mean, scientifically speaking - there's no real viable evidence of the existence of ghosts or spirits, and I've always assumed that if you were an Atheist that you couldn't be a dualist - but I have met self proclaimed Atheists who do believe in souls, spirits, ghosts, preternatural things with no scientific basis other than an unexplained observation.

On a fundamental level, is it really possible for the belief of such things to be consistent with the ideas of Atheism?
