It could be that some people do not hold themselves with such asinine certainty that they hold the knowledge to the creation of the universe. Some people might believe that as smart and informed as humanity is, we are still far from the point of understanding the universe and it's origins, and as such we do not rule out intelligent design, we do not rule out science, and we hold that the answers are still out there, as mankind's greatest mystery is not so easily solved. Of course, this is an agnostic mindset, rather than a religious one, but it still holds the belief in the potential for a God. I don't believe people should be blindly religious, but I also don't think people should be blindly atheist. Furthermore, I don't think people should be hateful to people and concepts that they do not agree with. They should be discussed and debated absolutely, but not shit on.
