Interesting thought. Perhaps the Egyptian relics should be repatriated to modern day practitioners of Egyptian polytheism. I believe the Kemetic Orthodoxy is currently headquartered in Illinois, USA.
Egypt abandoned monotheism for Christianity before surrendering to Muslims.
Hah. I’m going to intentionally pass on that one, my main point was that it is hard to make these decisions. The existence of surprising edge cases like yours just goes to show that it is a hard problem.
