I think that what Drich doesn't realize too well is that we operate under the very likely assumption that his particular god is non-existent, and hence, made up.
If it's made-up, then, as with all artists, inspiration must have been drawn from somewhere.
Greek tales were right next door, so it stands to reason that some parts of those styles did find their way into the myth being written up.
And places where you learn to read and write, must have been somewhat scarce, so the prevailing literary styles would be known to everyone who could write.
Other sources of inspiration must have been used, of course, mixed in with some genuinely new material and you get what we see.
