It had to be fucking fungus
Apparently trees used to lay fallen on the ground for millions (?) of years before fungus evolved to eat them, and since then there has been no new coal.
(I may be wildly off on the specifics but that is the gist I got from reading stuff here and there)
I swear fungi are the coolest and most "alien" lifeforms on this planet next to cephalopods ଳ
Or they're the original and we're the alien
