Argumentation suggesting there might be many "gods"
I'm not going to say this is true, but I find it plausible and interesting.
Let me paraphrase an argument by Nick Bostrom: http://www.simulation-argument.com/simulation.html
If you believe that human technology will continue to advance, and that we will colonize the solar system and beyond, then there will eventually come a point where we will be able to build enormously powerful computers (e.g. computers with the mass of Jupiter). Look at how far video games have come in 20 years and consider what could be done with such a computer. With a sufficiently powerful computer, we will be able to run simulations of our ancestors' lives with accuracy. In fact, we will be able to run such simulations a great many times.
Presumably the ancestors living in the simulated world will have minds and feelings just like us - their minds do not depend on the substrate (e.g. brain, silicon, or other) in which their mental and neurological processes are executed. Now, if the number of simulated ancestors is very large in comparison to the real population of people, then the question is, how do you know you aren't living in such an ancestor simulation right now? Statistically, chances are that you are one of the simulated beings and not a "real" person.
If you accept these hypotheses, then it seems that "above" our simulated world there must be beings which are essentially god-like with respect to us. It is also quite possible that there are nested simulations (simulations within simulations), and that our "gods" have have their own "gods".
