Because its not an isolated fluke.

Conciousness developed over millions of years. Thousands of different animal species, including humans. Nothing came from nowhere. Giraffes are tall because they need to reach leaves in high places. Sharks have gills so they can breath underwater....these kind of attributes developed over millions and millions of years. Think of all the animals who didnt make it because they weren't suited to the enviroment. Did god put them there to fail?

Saying "God did it" is the biggest cop out of all because it prevents you from trying to figure whats really going on. Religion encloses your mind in a box, "this is what happened...is happening....will happen...how you should live, think and act".

Imagine being born in a room. A single room. A person tells you that this is the world. You're never allowed to leave the room, you only do what your told because this is what you know. Reality is what you're presented with.

Imagine you're born in China and raised a buddhist. It's safe to say you'd believe in buddhism with the same conviction as you do christianty.

What boggles my mind is how people are told something. Grown up with something and automatically they believe it with such conviction that they are willing to die for it, kill for it, start wars over it.

Education (in the western world primarily) focuses on facts and figures...you learn things, you write them down in an exam and generally forget them soon after. This strengthens the side of the brain dealing with facts so that when you are told something it sticks in your head....religion, advertising, propaganda.

How is it even remotely conceivable that there is one way for everyone to run thier lives, one set of rules, morals and ideals that works for everyone. It can't happen. I believe in evolution because it's been proved by science...i can see how it works and that it makes sense. Beyond that I have absolutley no clue of the meaning of life and I never will....no one will.

I believe in ideas and philosophies.....you can change an idea....you can develop a philosophy. Your life experience shapes who and what you are. Not what was written in a book by other people hundreds of years ago.
