out of the mouths of babes...
well, I havent come across that many ppl (adults) who believe the earth is flat, though my Bible study teacher said her sister believed this. And she was like my parents age, so, you know, someone in her 60s or 70s.
I was like huh. I dont know what she got taught in school?! I was a bit concerned, so the next Bible study I bought along a book of NASA photographs from space showing the earth was a globe. I said to her you can borrow this book and look at the amazing photos, and show it to your sister.
