Here is a book that pertains to this topic. This is a recent edition:
The Sacred Mushroom and The Cross: A study of the nature and origins of Christianity within the fertility cults of the ancient Near East
John M. Allegro was one of the first translators to work on the Dead Sea Scrolls project back in the 1950s, so he brings some expertise to bear on the subject.
(I have a fine hardback copy of the 1970 first edition!)
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
