Had my first encounter with a real young Earther. I did a show at a Christian school. It's a small private school that is on a church property and the buildings also belong to the church. The pastor decided to attend. This year I do the scale of the universe and when I got to the size of the Earth I explained that Eratosthenes worked that out about two thousand years ago. I mentioned that two thousand sounds like a long time ago but that there were people here on Earth for much, much longer than that. At this point I was stopped by said Pastor. He said he will no allow "silly talk" like this on his property and that I must pack up and go! The teacher that organized the show tried to apologise to me, but I told him to apologise to the kids. The Pastor overheard me, and that really got him going. I do tone the show down at Christian and CVO schools, but I suppose you can never please everybody.
