Weird question, but I figured I ask this because in this webnovel/lorebook thingy I'm working on, I wasn't sure how I would describe these two races since they look exactly like humans.... and humans won't exist for another billion.
Is it best to describe what they look like the moment of their conception? Or should I do what I'm currently doing where I don't give details as to what they look like until like three chapters later where the narrator, a goddess, creates a prophecy revolving around Earth and then out of nowhere says "for some reason the humans look exactly like you".
I figured the latter would be a funny reveal? Narrative wise, the goddess is recounting the history of her zealots and they've already indoctrinated the universe at this point. Everyone knows what they look like, so I figured the best way to explain their appearance would be in an indirect fashion.
OR should I do both where I describe them, but the details seem a little vague to the point where I confuse the reader, giving them room to picture them as however they want, only for them to be like "WAIT, THEY LOOK EXACTLY LIKE US?!?".
