Sci-fi with aliens and primordial gods

hello! the book was:

set in a apocalyptic world where the main character dies and is resurrected by a primordial god

the main antagonist is a alien warlord

The main character is a girl who is pretending to be said god and then after her death the god takes over her body

The main antagonist travels to different worlds to conquer them, and the god is apart of their religion along with a mother-type other god

The main character murders the aliens and then leaves a mark that looks like two circles with dots in the middle connected by a downward facing v.

there is also a goat/alien priest.

it was mostly black and white, and I read it as a print

There’s also a specific scene where she says spread the word to a alien after taking a dog it was going to feed to it’s babies.

I believe it’s indie?

Thank you!
