Quote:Who would have made all of this up and what would be the motivation?
Power combined with credulity. You can gain power thinking you are right and completely be wrong. For the same reason Muslims have power in the middle east.
"Why would they die for a lie"? Is the wrong question. For over 3,000 years the ancient Egyptians truly believed with all their heart that the sun was an actual god.
The better question would be, "Why do you feel the need to cling to such an old story?"
