Choosing not to believe it is your choice, I don't have a problem with personal beliefs however founded or unfounded. I do believe that this is one area however where we don't have enough data to make an inflexible decision one way or another, there is a complete lack of hard evidence that it can't possibly be true and enough merit in the conceptual side of it to make the possibility worth studying.
My own views on it mostly come from a programming/game design background with a fair bit of experience in level/world design so I can't really expound all my experiences, etc. in a concise or cohesive enough manner to make much sense to someone without that experience but I've seen enough that I don't consider the idea completely far fetched - tho I find most of the commonly held (pro) views on the subject somewhat ludicrous.
