The fallacy in that argument is a completely different one. Either one defines "God" as encompassing anything that can create intelligence (in which case the statement is trivially true, and trivially useless), or not (in which case one concedes that intelligence can possibly arise from some other source, thereby undercutting the original assertion).
I used both of those arguments as examples of fallacies. The fact that we exist in a universe that can produce us does suggest that if there were multiple universes, they might not have had the conditions needed for elements and light and heat to produce life. That suggests that the entire universe has expanded and contracted, forming different substances and physical laws, more than once and likely several times. And each universe came into existance from what?
Perhaps probablity supports this argument, but the nature of it boggles the mind.
