I suggested that they rolled the stones on logs, pulled by horses maybe when I first heard that we don't know how they moved the stones. That was on an English Heritage tour at the site However I am told all the time it cannot explain the distances involved.
Nevertheless I am not open to the sciencist/atheism history of the human mind, which says if you show a "caveman" a radio, he would assume it was magic, because I do not believe we can read the minds of the people in the past. We do not know that they would think anything was magic, and when I see things I cannot make sense of, I do not assume it is magic, or God, I either ask if anyone else gets it, or I just accept that I do not know.
If you want the churches to be filling up with people, instead of leaching them, I repeat my basic point about how supporting belief in the preposterous claims of the Bible might serve the purpose better than emptying the church of any actual faith...
