Okay, let me make you all feel old real quick.
The first space mission I remember was the space shuttle's first mission. My parents got us up early to watch it on TV, as I recall. My dad was career Air Force, and while we never talked about it, I'm pretty sure he was proud of the connection between the USAF and the history of manned space travel. I remember a couple of times when he woke us up for something space-related, including an eclipse. I know that I was enough into the concept of space travel that a teacher's aide stopped me in the halls to tell me about Challenger, because she knew I would care. I was probably in third grade.
To be perfectly honest, I'm not all that into hard science fiction. Most of the sci-fi I read is more about people than science. I'm not good at advanced math, though I am the fastest person I know at calculating tips. (Faster than friends with smart phones, sometimes!) I took physics in high school, though I didn't learn anything in particular. I've never taken chemistry. I've never taken calculus. I don't understand a lot of the technical stuff that gets discussed around here; some of the jokes about how ridiculously ignorant HBs are in science go over my head, because I don't understand the concepts, either.
The first I knew that there was anyone who doubted the Moon landings was when I read Phil Plait's book. It frankly stunned me. I may not know a lot about science, but I do know a lot about history, and I knew there was no way a Moon landing hoax would still be a secret. It also doesn't take much to know that the science doesn't work, either, but I'd never looked into it. I joined what was then still the BABB, and I made friends. I joined here because, much as I appreciate (most of) the restrictions of what I still call BAUT, I do like having a place that's a bit looser with regards to politics and religion yet still reasonably polite. But "reasonably polite" is still really important to me, so I don't venture into most of the places where hoax belief is discussed these days.
