A prehistoric cave (Aware)

(being reworked ) (Story type 1: Like an isekai of some sort?) ( story type 2: Kelly is The goddess creating a new Adam and Eve type story line only the female is definitely dominant and probably impregnates the male somehow species type may vary)

Jack awoke in a dark area with a slight glow. Looking around it was clear he was in some kind of cave with luminous glowing crystals in various colours. Getting up and feeling himself it was clear something was wrong, he didn't really have a physical form, he was more and ethereal ghost of a man he used to be. Floating round the cave he observed many cave drawings, figures of creatures on the wall, humans of course but also others mythical in form, something that looked like a large centaur , something that looked like a much smaller centaur, a dragon like being, tall elven people's as well as an equally tall kitsune like race, something that looked vaguely bird like and something more serpentine, an arachnid and many more options ( ill add more if I think of them) and finally a figure of angelic form.

Jack was trying to figure out where this was or what was going on, he thought really hard trying to remember if anything had happened before this that could explain where he was or what all these crystals and their colours meant.
