More than a decade ago when I was teaching a class on creation, I heard about some Christians who believed in a flat earth. I was aware that some people were online promoting a flat earth theory but assumed they might just be evolutionists trying to mock Christians.
Apparently, there is a percentage of Christians who believe in a flat earth, deny that men walked on the moon, and even deny the Holocaust ever occurred. One flat earth documentary denies the existence of other planets and denies that stars are far away. As you would imagine, it requires a lot of mental gymnastics to reject the established facts of science and history.
Long before we had pictures of the earth from space, we had evidence of the earth’s curvature. This included the shadow of the earth on the moon during a lunar eclipse and the observation from people who would watch ships sail off in the distance and then slowly sink below the horizon.
 Of course, we have so many more pieces of evidence. I have had an astronaut who walked on the moon in my Sunday School class. I have had another who held the record (until recently) of spending the greatest number of days in the International Space Station. And all of us have pictures and videos of the earth from space.
 Nevertheless, some Christians take Bible passages out of context, like Job 38. Or they quote from a non-biblical source like the book of Enoch. A recent Albert Mohler podcast had a question from someone who asked if a man who believed in a flat earth should be disqualified from being an elder in the church.
Dr. Danny Faulkner (Answers in Genesis) has written about the flat earth phenomenon, and apparently has a book coming out on the subject. That may be a good resource to share with a flat earther, though I fear it won’t make much of a difference.
