Zeus was the first of the gods, but before he could become ruler of heaven, he had to avoid being swallowed by his father since his father had to swallow his kids, and the reason is that he felt that his kids would betray him one day, and it was true. The reason is that after Zeus made his father barf up his brothers and sisters to help him in the future to dethrone his father named Cronus. A disgusting name of terrible proportions. He demanded that poor people were thought of as real people, and not things like gardening tools, or pieces of trash.
