Hang on, Gordon. A claim is not a question.
The question "Was there a resurrection?" is not invalid as far as I can see and indeed it has been the bread and butter of atheist historians like Bart Ehrman and Richard Carrier for years.
You had me going for a bit but of course, your comment didn't stand up to closer inspection.
Bart D. Ehrman concurs, highlighting the insurmountable challenge in demonstrating miracles historically: "Even if miracles are possible, there is no way for the historian who sticks strictly to the canons of historical evidence to show that they have ever happened."

Not quite sure how you'd support your comment that the question "Was there a resurrection?" has been Ehrman's bread and butter. As far as I can see, his thought has developed fairly logically from his follow-up on Schweitzer's thesis "Jesus - apocalyptic prophet of the new millennium" (Jesus as a mistaken prophet), through sifting out the possibilities of textual corruption in "Misquoting Jesus" and on to "How Jesus became God" - in other words, how people interpreted what they thought about the figure of Jesus and magnified this image into an ever more grandiose Christology.
