I try to use real polytheistic religions for inspiration in D&D. Gods exist. There are stories about them. There's no concrete evidence of their existence. Everybody has different stories and different gods, and there's a general polytheistic syncretism that says "You worship a sun god too? Well sure, I can worship my Ra in the temple to your Sol--I'm sure they're the same dude even though he asks you guys to do some really weird stuff. I guess he must just like us better, but I'll respect what he asked here since that's where I am." So in my current campaign I provide my players a list and tell them "you're also free to worship any god you like and should expect people to see it as an 'aspect' of one of these major ones, depending on what you say your god does."

Here's a snip of the list contained in my setting handout.
