I've wondered about chem trails, aliens and many theories. I've read many conspiracy theories, but they're all ideas without evidence. Hard evidence, not books, or reportsfrom the internet.
Now I may sound like a skeptic but I most definately am not hehehe.
Go to
http://www.orgone.com you may find some interesting information there.
As for aliens it's my belief they're not really from another planet but are projections of the 'devil' and his forces. So are the 'lizards" (that one had me for a while though).
When you start studying chemtrails, you're bound to follow a path of information that's aligned with aliens, 'the greys' and the reptiles. many people will tell you the greys are a projection of the lizards, but then in turn they too (the lizards) are a projection of some demons, a demon, or the devil. When you get closer to the source it becomes clear and easy to think about (for me).
Once again, all theories but it's fun discussing. To deny all evil is ignorant, I think the skeptics should keep an open mind, as well as the believers. Hey, if I'm wrong, then I just learned something... which is why it's so hard lately to believe pretty much anything... it's all like a ball of flufffffff for you to keep thinking about instead of doing something about it (evil).
