Here's what I've never understood about the argument that the universe as we know it is too complex to have been formed by chance and that it must have been created by an even more complex being.

Doesn't that argument then raise another issue, namely, that a being as complex as God had to have been created by something even more complex? He couldn't just have happened, could he?

If you buy the argument that the universe couldn't have come into existence on its own, how can you buy the idea that God existed on his own? Seems to me you can make a strong case for either idea. And if you want to believe in God, that's fine. But I find it hard for you to dismiss the arguments of people who choose to believe something else.
