No offense intended here, but reason combined with evidence leads me to belief in God. To think that all creation is some big accident or something, without a prime creator, is unreasonable. As far as the "the family is stupid" comment, the Bible says that "a fool believes in his heart that there is no God", or words to that effect. Stupidity is a relative term. Some are stupider than others.
I can understand agnosticism to some extent, but never atheism. Just because there are a lot of religions in the world, doesn't mean that somebody isn't right (I believe Christianity to be the correct one). Much like there are a lot of philosophies in the world, but we know conservatism to be right! I personally believe Jesus died for everybody, regardless of what they believe (in the VERY long run). This opinion is probably as unpopular as atheism ;-)
