Why is 'god' a possibility?

Please elaborate. I'm not sure what you mean.

I also don't understand how modern science says it would be rational for me to be agnostic towards Dr. Who. I know 100% that it's a fabrication that is shown on tv for entertainment. Not one thing about it has a bearing on reality because it was dreamed up by men, just like the concepts found in religion and eventually their god(s).

Can you be absolutely sure that what happens on Dr Who is not, in fact, the real reality? Can you state with 100% certainty that there is absolutely no possibility that science and logic does in fact work as shown on Dr Who and all the events shown actually do happen, but wool has been pulled over the eyes of humanity by a powerful telepathic alien race, while another alien race is trying to tell us the truth by subliminally influencing the minds of the writers?

Or perhaps, there is in fact an alternate universe where things do work as shown on Dr Who and the events shown do happen there and someone there has built a machine to telepathically broadcast those events to other universes. And the few people in this world who receive these broadcasts become the writers of the show (or really devoted fans).

The point is, something like 100% absolute certainty doesn't exist in modern science, because, if it did, science would stop being self-correcting. While this facet is necessary for scientific progress, it still requires us to allow for the existence of any and every arbitrary idea - no matter how far out there it may be.
