The human ignorance factor was quite high in comparison todays knowledge of the world we live in.
For example lighting and thunder, v olcanoes and earth quakes.
Storms and floods devastating vast amount of areas.
The list was along one, the gods gave explanation for these events.
Also attaching to these powerful gods was deemed personal beneficial to the wants, desires and needs of the people who
believed in them, hence the many gods of the ancient world and cultures.
Once people made a sort covenant and worshiped their god or select gods ,
breaking away from that relation was deemed to be futilely dangerous,
perhaps too for the high priests that were said to be a direct connection to the gods. $$$
