Did people in the 60s actually think The Jetsons was a real concept for future living? Or Star Wars or Star Trek? Or was it just entertainment?

Milton blindly wrote Paradise Lost. Shakespeare wrote Hamlet. There was Beowulf and Sir Gawain and Oedipus Rex and Ramayana and Tao Te Ching.

Did all of those people literally believe all of that?

No movie franchise has ever made as much money globally as the "Marvel Cinematic Universe."

Imagine if four hundred years from now someone asks, 'Well, there was _______ who watched a Marvel movie. How much influence did that have on the published mathematical proofs?' Fuck all.

If God isn't writing about math in his book, then God isn't influencing the science.

Just because most of us have watched a Marvel movie doesn't mean it had any damned influence on anything else in our lives. Culture is much more complex than one religion, especially when interpretation of that religion changes dramatically over time. Christians 400 years ago would hate Christians now and vice versa.
