| As soon as you postulate the existence of an independent metaphysical reality, such as the Platonic world of forms, or even the idea of good and evil, you will eventually have to resort to God to back it up.
One or the other: If you believe in absolute truth, you're going to need God eventually. If you believe there is a set of truth somewhere out there that we are uncovering as we go, you're going to need God eventually. If you don't like this, re-evaluate your assumptions.
Yes, we made God up, but it doesn't mean he/she isn't real. We made war up too, and it's pretty freakin real. But we can also unmake God. (In our own image?)
