But you last sentence is misleading. History shows the exact opposite of your claim of happy, joyful people.
p.s. Religion IS Superstition.
The history I have been reading shows that they have very few wars. Loved music and entertainment. Food was a big item. Being a chef was a good career. One temple for example received over 5M flower bouquets in one month. Which show the people had the time to grow beautiful flowers. People don’t grow flowers unless they have grown all the food they can use first. The women had time to wear beautiful cloths and use makeup. They wore beautiful jewelry. They had their hair done in fashion. They love their pets to the point of mummifying dogs and cats. From what history is showing us. They had the best medical practices at the time.
Where they had problems were in the area of alcoholism. A side effect of plenty of beer and wine.
Note, you have to read the new history out about Egypt. The old theories are not holding water.
