I paid attention im middle school and we learned it was dead dinosaurs. I often wish i paid less attention, the shit i learned in school is insane. Or not even learned per se, but things a teacher told me or mentioned and i saved it as a fact.

By far the worst one i remember was a teacher talking about the ozone layer, the hole in it and what it means. Then he casually mentions that because of that, new Zealand is basically inhabitable. Children have to wear special suits if they go outside during the day. I had no idea where new Zealand even was on the map, i don't think i heard of it before, but i kinda always imagined it as what the surface of mars looks like. I was absolutely abysmal at geography, and never cared for it as a kid, so for waaaay too long, i had that thought in my brain that there is a country that looks like mars, and there live people that are like reverse Inuits who wear their special gear to go outside. At some point i watched the movie "bad taste" and at the end i was like: wait, THAT'S new Zealand?!

Great info, bad presentation lol.
