Based on how complex a being/beings would have to be to create the universe and based on what we know about the universe is there any way to calculate the probability that a god/gods exist and created everything? For this question I just mean any god/gods in general not necessarily the god of any particular religion. Also how long would it take for a species to evolve to the complexity necessary to qualify as divine?
The reason I am asking this is because creationists try to use the fact that the probability of any given universe being conducive to life is extremely small to argue for Intelligent Design so I want to know what the probability of a god existing is by comparison.
