Why do you not believe in God?

hehe, yes, that is the conclusion, but it is question begging because you are using it in your premise.

Everything that begins to exist must have a Cause.
Everything that doesn't begin to exist, doesn't have a Cause.

Can you see a distinction between the statements? I believe both of these are true.

If something didn't begin to exist, it would be eternal, not in need of a cause.

If something began to exist, it would be in need of a cause.

lol, I'm going to apologize to the OP at this point for douchejacking the thread, I figured this would happen.
Ok, let's see. where to begin. First of all, we were arguing about how sound an argument is logically, not your preference, or your perception. What you wrote is not a logical argument so I won't bother to refute it.

Here's a little tidbit of reply though. Causation is a temporal phenomena. You have matter in state A , then you have a cause, and then you have matter in state B. Since time is a property of the universe, what you are looking for is THE CAUSE, not A CAUSE (do you see the distinction?), meaning god, meaning an undefined entity.

Here's something else that is wrong with your ... argument? Every one thing that begins to exist has a cause. Meaning that everything within the universe has a cause. The universe is not a thing, it is the set of all things. See Russell's paradox regarding sets. Therefore the argument fails because you are making a categorical equivocation. Here's your argument now.
1. all Smardorfs that exist are purple
2. Marsrdorfs exist.
c. Marsrdorfs are purple.
