I found another debate Anthony Flew (right) was in before he became a theist. He debated Dr. Gary Habermas (left) in 2003 at Cal Poly, San Luis Obispo. This was more of a discussion that a debate. It looked like as if Anthony Flew was given a chance to ask his own questions about Jesus' Resurrection and have them answered by Habermas. It's very informative.
Gary Habermas pointed out that the Resurrection is a more probable explanation of Jesus' post-crucifixion appearances than multiole groups of people sharing a vision of seeing Jesus because we don't have any examples of multiple people sharing the same vision.
