Is it just me, or is it vaguely racist how dismissive that article was of "ancient civilizations" and the idea that indigenous myths might be retellings of the Younger Dryas impacts? I feel like there's always aggressive pushback from "modern scientists" whenever the idea comes up that indigenous myths speak of real historical events. It feels like, in the US and Canada particularly, Native Americans aren't allowed to have histories - that the history of Native Americans began when white settlers arrived to write those histories down. They want to pretend the thousands of years of history passed down through tribal oral traditions never existed at all and Native peoples simply existed, like animals, without memory of past or hope of future, until civilized Europeans brought history to the Americas. When what really happened was most of the people who remembered those oral traditions died in the colonial apocalypse, and those settlers danced on the graves of history.

All that is to say, the science might be one way or another, but the dismissive attitude taken towards oral tradition and mythic history really rubs me the wrong way.

I really dislike how it's become a conspiracy, because now it's hard to pin out the good science from it.

Other fringe theories are fun to think about and debate, like the planet 9 hypothesis, which is becoming increasingly unlikely, and to a lesser effect modified Newtonian dynamics (MOND). Fringe theories are important to push forward the boundary of knowledge, even if most of them are wrong.
