Youtube by way of NASA.
Never did believe we went to the moon for many years. Have you seen that thing at the museum? Yeah, right, we went to the moon in a bucket made out of gold tinfoil and broomsticks. Don't think so.
Saw some YT videos a few years ago that made me rethink what I had never given much thought to before. But it's all right there before your eyes, totally flat. No curvature to be seen anywhere.
I reread the Book of Genesis and realized it all describes Creation exactly as we see it. God does not err, nor does He lie. His Word is Truth.
Awesome to hear! Youtube can be helpful, but full of contrary and atheistic opinions on flat earth, so I'm glad to see you made it through intact. Sadly, many people are simply not able to discern, or think it doesn't matter. Stick around and watch the fireworks fly! We have lurking several critics of the first kind, literally unable to grasp this beautiful Catholic teaching.
