This is a good video, imho, and not about flat earth, mostly.
The good thing about people who distrust NASA narratives is that they're akin to anons.
This creator does a really good job of tying together various theories and queries from the truth community (including Q) and making it a digestible, albeit long, presentation.
His name is EwarANON, and I believe he's doing good work. He doesn't try to convince anyone of anything, just acknowledges why there might be so many questions and gives some possible answers, mostly to historical technology and resets, (Tartaria/Mudflood theories) not so much flat earth here.
It's best to keep an open mind when our education and availability of knowledge has been hijacked.
He, along with may others, are just trying to figure out what's what and dissect the truth from the mountain of lies and false narratives we've been given.
I believe your rejection of flat earth's premise is irrelevant to this video's information and its value.
