Atheist Viewpoint
In my opinion, religion is nonsense. I respect all religions and have nothing against them but religion to me is the cause of all wars. But how do we know who created the world? How do we know that someone or something wasn't teaching cavemen to advance, and who is to say that aliens don't exist? It doesn't make sense that some worship Allah and and some worship Jehovah and each group claims that theirs is the only deity, yet you have people worshipping more than one deity.
