Any blackpills about Neanderthals?

Watching a new doc on Netflix abou Neanderthals. Seems like a bunch of fake news.
"Oh this 44k year old bone has a fragment chipped off..this concludes they were cannibals "

"There's ancient pollen next to a skeleton...this denotes flowers alluding to a burial service"

U wot m8?

Is what's being told to us about Neanderthals fake and ghey?
