Some have said that the first guys to milk a goat stored the milk in
a goat rumen (first stomach) and the stomach lining enzymes (rennet)
made cheese of it.

Archaeological evidence for sufficient domestication of animals to
allow milking first appears ~10kya; long after H sapiens arose.  K

I don't recall the first instances of fruit storage or discovery
contexts.
