Graham, if you are interested in looking at more of the scholarship relating to the historicity of the resurrection you may want to check out this site and post: https://www.reasonablefaith.org/writings/scholarly-writings/historical-jesus/jesus-resurrection/

Also, historian of the first century mid-East, N.T. Wright has written extensively on it. Here is a great one:

Resurrection of the Son of God.

if you would like to point me to some of your preferred sources I'll be happy to check them out.
