I just got back from an SFF convention. One of the panels I attended was a discussion of mythology. One of the ideas brought up by a member of the audience was the standard fantasy trope that gods require belief to exist.

This has been around for decades. It even has its own TVTropes Page {I accept no responsibility for lost time or sanity spent on TV Tropes}.

It struck me a bit afterwards that despite being used for theist worlds, this idea is the strongest anti-theist statement that can be made. It embodies the concept that gods are human creations and that they derive all their capabilities from the humans who make and sustain them.

Yet this idea is accounted as theistic, which now seems very odd to me.

What do people think?
