However, now that I'm an adult--not much smarter in math and science--after watching a few "flat earth" documentaries (including Rear Admiral Richard E. Byrd, an American Naval officer who specialized in feats of polar exploration, who spoke of an untouched resource rich --coal, oil, minerals, uranium, etc--land as large as the U.S. off the south pole that needed further exploration, but resulted in an International treaty that banned all exploration of that area in 1959 after his death) and reading a little from the International Flat Earth Research Society, I still have a few stupid questions:
Architects, engineers, and pilots must factor in the curvature of the earth into their projects, flights, right? So if they do, isn't that proof of a globe? If they don't, wouldn't they ask, "why not?" (Someone claimed NASA uses "flat-earth" calculations)
Do airplane pilots constantly correct their altitudes downwards so as to not fly straight off into outer space?
Why aren't there any realistic videos of our spinning earth? Why no new non-composite pictures of earth?
Why was an international treaty put in place banning any country from doing basically anything in the area Byrd discovered? With so many resources for corporations to exploit?
Why does the UN use a flat-Earth map as its official logo and flag?

What about day/night cycles and seasons? Shouldn't there be an am/pm switch every 6 months?
I think flat-earthers claim everything revolves around us:

I am certainly NOT convinced that we live on a flat earth, but those in charge of explaining our reality are so good at making lies sound truthful, so good at manipulating, deceiving, and gaslighting us that not to question and examine everything we've been indoctrinated to believe even when it totally contradicts our experience or sense perception is, in my humble opinion, the true definition of insanity.
