I wonder all the time whether or not if Greeks literally believed in their gods and myth or not. A lot of Christians do not literally believe in the events of the Bible as historical (while some do). Is that comparable to the general attitude in Ancient Greece, with there being individual cults that literally believe in their god/diety? Is there any way we could reasonable assume to know?
I like the think that in the far future, after American culture as it is doesn't exist, people would discover our love for say, Batman, and think that we worshipped him as some kind of protector, and that the comics and films are our cultural myths.
Thank you so much!
More can always be said on the matter, as no answer is ever 'final'; further answers are more than welcome from anyone able to contribute. For the meantime, OP, you may be interested in the following previous answers. The first two cover how the Greeks regarded Mount Olympus, and offer a view into how they thought; the third is a more general treatment of Greek belief.
