William Lane Craig is said by atheists to be someone atheists should never debate. Atheists self-admittedly get trounced by William Lane Craig. Here is Common Sense Atheist on the matter:

Let me repeat. Craig has done 20+ years of Ph.D+ level research in the two fields he debates, has published hundreds of academic books and papers on both subjects, and has been debating since high school.

So yeah, that’s right. You are not qualified to debate William Lane Craig. Richard Carrier? Austin Dacey? Quentin Smith? Bart Ehrman? You are not qualified to debate William Lane Craig. Louise Antony? Christopher Hitchens? Eddie Tabash? You are not qualified to debate William Lane Craig. Frank Zindler? Gerd Ludermann? Hector Avalos? You are not qualified to debate William Lane Craig… Mark Smith? John Loftus? You are not qualified to debate William Lane Craig.
“Okay, well, is anyone qualified to debate William Lane Craig?”
Nobody comes to mind…

Elsewhere common sense atheist points out that William Lane Craig has won almost all his debates against atheists and then lists them.

Although Christians may not agree with everything William Lane Craig believes, we should take note of his demeanor, his argumentation style, and his systematic way of thinking. Here is William Lane Craig debating famed atheist Bart Ehrman.
