There was no Curse found in the Tomb of King Tut—BUT there were curses found in Other Tombs! So the curse thing did exist in Ancient Egypt but they used Magic and Science side by side in their medicine and buildings. They were the best doctors in the Ancient World. They even put medications in the eye make-up everyone wore. Eye infections were unknown to them something that can’t be said today.
The ancients were a bit OCD about eye ailments, that was the number one medical specialty for at least a couple of thousand years. In Herodotus there is a tidbit about the Egyptian use of crocodile dung (processed somehow, but still...) for eye ailments; naturally they used a magical-thinking approach, but (basically through trial and error) identified a real remedy — in the 20th c it was found to contain a natural antibiotic.
As far as curses go, well, those are interesting from a sociological perspective, but are balderdash in reality.
