Something odd

I can't believe I'm writing such a far out subject as the first paragraph post, but I can't think of anything else to write about!!! I'm very unsure of the boundaries and subjects as to which we are supposed to write these posts, so excuse me if I ramble. I asked my friend for help on what to write about, and he is an avid alien believer. Before I met him I really never thought either way about whether aliens exist. It's known as such a "weird" subject to think about, so I just accepted that it is a possibility but I could never know for sure so I needn't think on it. After he brought it up a couple times, I started to think a little more. Why is it such a negative feedback for aliens? I'd seen him mention subjects like this and other such theories to people at parties as an interesting conversation, who would respond like it was too much for them to even think about. What social thing is this? I figure it could be a common waryness of the unknown in people, or it could be religious. And what is religion to do with aliens, since it doesnt fit and we have this social ritual that is thousands of years old. I don't think something that socially ingrained can be forgotten so easily for science. I consider aliens part of science, since by aliens I don't just mean little green men from mars, I mean even bacteria. Bacteria is small, but it is still alien life! I also don't mean in any way that religion is all bad with science, since it's always changing and it really brings people together. It's just that people might not know how to think of aliens in the same picture as their religion. Or, maybe, it's just a really strange subject.
