I never got this line of logic because how did they come about to begin with? they could not have created any one thus aside from getting power why worship them?
Davies already hit this, but adding on: the situation is often either "forced" upon deities after a certain point (e.g. they
used to have enough power to create things and exist independently, but that power has waned/disappeared or been expended/taken away, and now they need to replenish it) or is a natural step in the "evolution" of a deity over time. E.g. deities are "born" in some way that doesn't depend on worship, but after they "mature" they require it. Forgotten Realms took the former path, with Ao the over-deity (a different class of being from regular deities, regardless of power) punishing the gods by
making them dependent on mortal faith--taking away their self-sustainability. (As others have shown, the whole thing in FR is pretty fraught, so what
exactly this meant isn't clear, but
something changed and deities became at least
more dependent on faith than they used to be.)
The classical notion is that there is a single entity who created the original deities, who in turn created others, who then (often several generations later) created mortal life. In this notion, while the deities get power from being worshipped, this adds to what power they already have, and they do not require it to exist, but will nevertheless stop existing in the fullness of time.
You saw something kind of like this in Egyptian mythology, coupled with the "natural life cycle of deities" stuff I mentioned above. E.g. Ra eventually retiring to his solar barque full-time because he's become too old to be a "living" god anymore, and had lost the faith of most mortals, while his father Nun (one of the
really obscure Ogdoad) remained a nigh-omipotent but not particularly
person-like entity/force/being. This was also used in various places to explain pantheon syncretism or the addition of new gods, whether by adoption, division of an existing god, or divine reproduction: the old gods dying off to give way to the new.
A more modern notion is that the deities are created from mortal belief, having no power beyond what they are given by this, requiring worship to continue existing and dying without it. In this instance, as you say, they did not create mortal life, rather it created them. As to why you should worship them if this is the case -- it is typical for this school of thought to suggest that you probably shouldn't.
Yeah, it's...pretty much just the idea of constructivism applied to belief-shaped magic, and then deriving from that maltheism, that any so-called "gods" that do exist are inherently bad and wrong (because they deceive people into worshiping them) and deserving of nothing but scorn. It's a pretty old and tired trope at this point, since (as others have said) you can see examples of it way back in the 30s, and it was commonly used as early as the 60s with original series
Star Trek, both played straight (the ep with Apollo) and tweaked slightly (the multiple episodes with powerful D&D-god-like computers that rule over societies forced to remain at primitive tech levels, e.g.
Return of the Archons and
The Apple).
OK, that right there is a great thing to add to a planar campaign: <snip>
While I'm not going to steal this idea proper, I'm totally going to riff off it for my DW game. Thanks!
That is a 100% improved way of handling their mythos: It's the Office.
I've long thought it would be entertaining to roll it back just a little further than that: Divine
High School. Bahamut as the golden boy in seminary and Boy Scouts among other things, with his hyper-rebellious sister Tiamat barely avoiding expulsion. Kord and Moradin as the guys in shop class--Kord because he's not-quite-delinquent but really just doesn't mesh well with organized schooling, Moradin because he's a military brat who's big on the whole "self-sufficiency" thing. Everyone knows Ioun is valedictorian, though she's got big competition from both Corellon and Asmodeus (though everyone thinks the latter's got some secret advantage). Etc. All sorts of great sibling drama, relationship drama, politics, factions...it's pretty much perfect, you'd just have to find some way to integrate the whole "worship and devotees" angle.
okay, the first I can understand but asks the question why do we not just go worship that guy given that they are the best and all-powerful?
As said above, they often don't care, or aren't really capable of
noticing something as small as mortals. If gods are to us as we are to ants, then these super-gods are to us as we are to
molecules. Too small to see, too small to really care at all about, even if theoretically they're important to us in some way, we could lose
trillions and never notice.
the second flat does not work for an epic history as they would have never been born and are simply dreams that got too big for their boots.
Dreams can be powerful things though, even IRL. They can motivate entire nations. If a dream could have
sapience and
willpower, and grant magic to others, how much more could it achieve? And if these dreams can exist for thousands of years, continuing to gain knowledge throughout that time, who's to say they couldn't be epic? Remember,
our epic context doesn't go any further back than about 4100 years (the Epic of Gilgamesh, ca. 2100 BC). There's no reason a deity couldn't have existed for double that length of time--far longer than any history humanity can trace.
plus why would the game even have them as they are limited in the variety of plots overall?
Deities are often more problematic for being too
powerful than for being too
limited. Limits on divine power are generally desirable to a designer.
I have considered a way to do a subjective god presentation but it is super complex and I do not think any one wants to hear it.
I, personally, am always up for cosmological discussions, but I understand if you don't feel it appropriate for this context.
then why make it an entity and not a mindless process? or make it a being who dreams all the other stuff into existence?
A mindless process is usually inert once it's finished--or needs a reason it's not
still doing the same things it did to start with. Mindless processes also have the "okay well...why did that mindless process happen?" infinite-regress problem.
"A being who dreams all the other stuff into existence" is, more or less, the same as the aforementioned "primordial chaos deities" (like the Ogdoad, or the Greek
Khaos, or the primeval underground fresh-water ocean
Abzu/Apsu in Babylonian myth). It's a little more complicated than that, because (as noted) Ra is able to
talk to Nun in some way, and receive things from him. But there's still an idea that these beings in some sense undergird reality in a much more abstract, and indeed dreamer-like, fashion than any of their deity "children."
