You assert: "Virtually all the "evidence" for the spinning ball earth comes from NASA -- it requires trust in NASA as a source. I can't grant that, sorry." (I have no problem believing the truth told to me by a 5-year-old who says 2 plus 2 is 4; that does not require me to trust him when he says the tooth fairy is real.) No need to be sorry if that is what you sincerely believe, but again your statement is preposterous on its face. There are major countries besides the U.S.A., and there are all kinds of other schools and institutions that have carried out space, astronomical, and cosmological studies that have over many years come up with evidence for a Globe Earth -- some even before NASA was even founded.
OTHER space agencies? You SURE you want to go there?

Have you SEEN any of their footage? It makes NASA look air-tight and flawless.
I've looked into each and every one of your claimed "Globe Earth slam dunks" and they're all baseless. Either they lead to NASA as the only source, or they were proven false.
Don't forget that I was not raised in a tin-roof wooden shack in appalachia by toothless parents who were siblings, who were uneducated, simple, and taught me flat earth from childhood. That's what Globers tell themselves about Flat Earth proponents, because it makes them feel better.
The FACT is that I went to public school, graduated with decent grades, got good grades at a strict Seminary for 3 1/2 years, am a software developer by trade ("no dummy"), have been interested in "space" since I was 10, have been out in the world the whole time, and I know more about the Globe paradigm and "outer space" than most Globers. Most people simply haven't looked into it. JUST LIKE ME before I started investigating Flat Earth. In other words, most people believe in the Globe for a few simple reasons:
Everyone around them believes it
Movies and propaganda
Authority (including school, college, etc.)
Taught this from the first day of school, with the globe on the teacher's desk
In short, they believe it out of IGNORANCE. It doesn't go any deeper than that. OF COURSE millions of people will be deceived in such a situation.
