There is a tendency in FR threads for some to reason from the necessary existence of God, directly to the existence of the Christian God, complete with whatever attributes some particular church or demonination ascribes to God.
Second, it is quite reasonable to hypothesise that God exists only through the existence of the universe; that is, God cnnot be said to have attributes except those those that manifest themselves through existence. I used to think this was called Deism, but correct me if I'm wrong about this.
Indeed, it is impossible for me to speak of someOne I personally know as a hypothetical. So I will always speak of God in the Judeo/Christian context.
There are of course other concepts of God. One of these is the "collective consciousness" to which you are speaking. But that would not be reasonable in the context of a Creator, IMHO, since there is always a beginning, a cause - and a collective consiousness follows.
