What's there to redpill? It was a lowland above sea level during the ice age, European hunter-gatherers roamed there, and may or may not have had some modicum of civilization/early settlements there that are now under water. You can insert any level of fictional wiped out ice age civilization here, from stone age huts to Vimana flying castles dropping nukes on nephilim demons.
Personally, I don't think purely oral tradition can preserve anything resembling reality for thousands of years, many hundreds of generations. Any story will get warped completely out of recognition within a couple centuries unless it has a written form to doublecheck against. That's why Gilgamesh is first, because they put it on thousands of cuneiform tablets to check against what the bard is saying at the feast.
