One more time, why there most certainly are not any gods.

First let's define the word "god". Let's call this thing what it really is, a magic fairy, instead of reversing the letters of the word "dog" and calling it that.

The short version of why there are no magic fairies is this: There's no magic in the universe.

Wasn't that easy? It's not necessary to write an entire book about it, for the same reason it's not necessary to write a book to explain why leprechauns are not real. Idiotic ideas (leprechauns, Easter Bunnies, magic fairies) should be thrown out immediately. These ideas are so ridiculous it would be a waste of time to talk about it.

However, for the benefit of any stupid people reading this (all theists and all agnostics), I will write a more detailed explanation for why anyone who believes in a magic fairy (or thinks a magic fairy can't be completely ruled out) is a fucking idiot.

All gods were invented to explain the natural universe (for example how the universe began, the development of solar systems, how life developed in at least one of those solar systems and probably millions of solar systems).

Every god ever invented is a god of the gaps. Dishonest Christians (they're all liars) deny they believe in a god of the gaps, then in the very next sentence they stick their god into some gap.

Take away the gaps (this is called scientific progress) and you got a god of the gaps with no gaps to hide in. We have reached that point already. Science is complete. There will always be research opportunities in science, but all the basic stuff has been figured out. Magic fairies are not necessary for anything and they never were necessary for anything. A god with nowhere to hide is a god who doesn't exist.

If you still think there's some hiding place for your magic fairy of the gaps (most likely because you're an uneducated moron), that's no excuse to invoke your invisible magical creature. Gaps in human knowledge are called research opportunities. They are not an excuse to stick your fairy in there. If everyone was as lazy as Christians and invoked magic for every unsolved problem, scientific progress would come to a complete stop. That's why virtually all of the top scientists in the world are normal people, also known as atheists.

One more reason to not believe in a magic fairy: If you believe in magic, you're a fucking idiot. Believing in a god is equal to believing in magic. If you think magic is real, then you don't know what reality is. If you think magic might be real, or if you think it's impossible to completely rule out magic, then you're as retarded as Bible thumpers and Muslim terrorists.

Theists and agnostics, stop being childish. Stop being superstitious idiots. Grow up. Join the 21st century where normal people live. If you're too cowardly or too gullible or too full of shit to do that, then shut the fuck up and get out of the way.
