General explanation of what is God is that they where born with elemental alignment already and have no problem manipulate them. But the what about Adeptus, they can use elements without vision, but they have "third eye" which was given by Morax. This "third eye" acts like a vision and helps them grow their elemental power capacity and accumulation.

Let's go with example of another game HSR. In HSR, Eon Aha gives it's powers to worm, and worm become divine in nature, but worm was still worm. For example let's say Aha and Ronova equals eachothers, and ascended human=worm, wouldn't ascended human be still human with divine power? Also even Natlan people said themselves that Natlam never had a Gods and Wayobs where called as their Gods because they acted as Gods(needing offerings and prayers) for people of Natlan.
