One problem is that the show is inconsistent in its definitions. Like, when they talk in this episode about gods who are fed by stories and are essential to humanity such that killing them would inflict terrible harm on the world, I don't think these are the same beings as the gods from outside the universe who have been invading the show for the past couple of seasons starting with the Toymaker. But it isn't made clear, and those are the only gods the show has directly acknowledged over the past few years.RE: No Gods in Doctor Who.
Now granted, sure, most of the time, the Doctor doesn't face Gods. And what constitutes a God is up for some debate. But sufficiently advanced alien, etc. etc..
Xoanon thought it was a God, as did Rassilon and the Dalek Emperor. Kronos the Chronovore might as well be a God, as well as The Bad Wolf, possibly the Guardians of Time. The Gods of Ragnarok call themselves God, and so did Sutekh. I don't recall, but I'm pretty sure Fenric was considered a God as well (or at least claimed to be one).
The Daemons were worshiped as Gods or Demons, ditto for Light (from Ghost Light) and Magnus Greel, and even the Time Lords themselves (by the Minyans, for example). Ditto the Optera, Aggedor, Ti, Akhaten, and Kroll. The Nimons pretended to be Gods. Ten fought The Devil (The Satan Pit). Omega, holding himself together out of sheer will could be considered a God of sorts.
The Doctor himself was seen as a household God in The Fires of Pompeii and the Face of Boe called him "the lonely god". K9 Mark I was worshiped by the Anubians.
And who knows what else I may have missed.
This is not exactly a new thing to the franchise.
And I really dislike that element to this week's episode. I thought the general concept of stories having power, which can be harnessed to inspire future generations or to power a metaphysical engine, was a really neat one and for the most part was very well executed. But when you tie that into those stories either powering or begetting actual gods, and those gods being essential to humanity, that takes the story in a theological direction that I don't appreciate.
