The main issue with your question is the word "the."
There are vastly many possible ways to define the word "god," any one of which
could exist or not. But most of those are also individually vastly complicated
and exceedingly unlikely to exist unless there is some causal process that
brought them into being, which in the eyes of many actual current human
believers of a particular version would disqualify them from godhood.
What probability do you guys assign to the god hypothesis being true?
