It's not really relevant and simply means Descartes should have phrased it better. However the phrase "Thought, Therefore existence." is what we'll use.
Why use that? It's not what Descartes said, and it's not what Descartes meant. So why quote him?

Perhaps "God" exists outside of everything we consider to be the universe or as as far as the observable universe goes. Perhaps he is an inherent aspect of the universe and exists sort of like a flight controller who is an inherent aspect of an airport.
So God is a part of the universe? Then God as originator of the universe also originated himself. So how is saying God originated the universe different than saying that the universe originated itself?
Also, "universe" means everything. Saying what we "consider to be the universe" or "the observable universe" changes the meaning of "universe" to some subset of everything.

For instance, if the need for an originator of the universe is imperative, why isn't there a need for an originator of God?
Dustin said:
Who says there isn't?
Again, if God is the originator of everything, then there can't be something (God) that was originated by something else.
[By the way, can we say "create" instead of the very awkward "originate", or do you intend a difference in meaning that is lost on me?]
Now, back to the beginning: what is your definition of God? It sounds like you are now saying that God is some entity that is a subset of the universe (a member of the universe), but that God is also the originator of the universe (but not necessarily of himself?) You don't see any logical problem?
You have not operationally defined God. Please review the meaning of the term "operational definition".
Again, I agree with your overall point: there is nothing that could possibly prove God's existence to me. Growing an amputed leg back, etc. could be the work of benign aliens whose technology is way beyond ours. Something like that might make a strong case for God's existence, but it certainly wouldn't be proof.
