This is more directed towards Christianity but I hope you get the meaning.
You won't believe in evolution but you would believe that some dude in the sky created everything on Earth because obviously it makes so much sense and has so much more evidence. Some guy 2000 years ago claimed to be your savior and claims that he will be back, yet in 2000 years of human history we have not seen even a trace of him (of course, not before countless killings have been committed in his name), yet you still continue to believe. You would believe in a number of fairy tales including a man on a giant ship with a bunch of animals floating on the sea during a giant flood, but an asteroid hitting the Earth and killing the dinosaurs is just impossible.
And worst of all, their main excuse is, "Why can't you just let other people be and let them believe what they want?" Yet they are the ones going around spouting their nonsense in people's faces, they are the ones who oppose homosexuals getting married, they are the ones who want to force their unreasonable beliefs into the public education system (intelligent design, prayers at school, etc.). What hypocrites.

Note: I know this is an obvious troll, but I'm making this post for others who don't understand. Sure, God doesn't seem realistic. However, that does not stop people from wanting him to exist. Think of it this way. Maybe you are poor. Maybe someone close to you is incredibly sick, and it is quite possible they will die. Maybe nothing goes the way you want it, and it seems like life is making you it's bitch. You might work as hard as you can to make your life better, but nothing works. In a life without God, you have no solutions. You have no hope. You know that things aren't going to get better. In a life without God, you still have no solutions. However, you still have hope. You believe that God will help you, or at the very least, you pray that he will help you. It allows people to live, knowing that there is a divine being out there. A being that protects them, as long as they adhere to it's laws. The know that they are not alone in their struggle. This is why many believe in God, or at the very least, why I started to. I don't care if God seems unrealistic. I just don't want to be alone.
