I guess I just listen to the news. Of course, I suspect that someone who thinks the world is flat and the sky is solid, with the sun revolving around the flat earth and the planets moving in epicycles may just have trouble understanding 7th grade science, Eppur si muove! I have looked through a telescope and seen the moons of Jupiter, My salvation is based on the blood of Jesus, not Gilgamesh or Noah, nor Balaam's donkey. If you insist on believing that the Earth is flat, just don't make Satan happy by preaching that when talking to one of God's lost sheep about Jesus.
