Hearth

Old English heorð “hearth, fireplace, part of a floor on which a fire is made,”
also in transferred use “house, home, fireside,”
from Proto-Germanic *hertha- “burning place”
from PIE *kerta-, from root *ker- (3) “heat, fire.”

And other cults and religions …

Cooking itself though, is a pre-civilized art. According to the video, we’ve been practicing it for a very long time, on the order of a million years, even before we had the honor of calling ourselves H. sapiens.
