One God

The argument made by Christians leads to the concept of a supreme being which created the universe, lives in a "world" beyond our physical reality, and sent his "son" to redeem us from our sins.

Say I accept the concept, but maybe not all the OT details.

How do you get to the notion that there is one God who is eternal and infinite? Why can't "God" (the creator of our universe) be from a race of other supreme beings? Why do these beings have to be "eternal and infinite"? If there is one God, how did he have a son?

The concept of creation and a heaven full of these "Gods" is not inconsistent with the belief that God is but one of a race of supreme beings. The arguments for God used by Christians are not inconsistent with the concept. It actually may seem more logical to some.

Ah, but there's a catch! If God is but one of a race of these beings, then he is no longer "THE" God, and our devotion to him in particular may not seem so necessary. Plus, we as a species may seem less significant if there is a whole race of Gods, rather than us as the only "soulmates" of the divine creator. Also, the concept then starts to sound more like Greek mythology when one travels down this path, and you wouldn't want your belief systems to sound like their silly belief systems.
