Why did sumerians think everyone had to keep gods happy?

Sumerians believed that the gods controlled all aspects of life, including natural events and human fortunes. They thought that keeping the gods happy through rituals, offerings, and temples was essential to ensure prosperity, good harvests, and protection from disasters. This belief stemmed from their understanding of the unpredictable nature of the world around them, leading to a strong emphasis on appeasing deities to maintain order and favor. Ultimately, satisfying the gods was seen as a communal responsibility crucial for the survival and well-being of society.
