Let me explain the origination of religion, how did religion
first came about initially.
Primitive ancient people that time were living in caves, hills
and mountains, they do not know that natural phenomena like
lighting, thunders, earthquakes, floods etc are not acts of god.
their lifestyles were hunting, eating their hunt, protecting
their tribes and procreation. so they begun to think that there
must be a god, if not who are creating all these natural diasters.
so they begun praying to Sun, Moon, rivers, sky to seek their
protection and create less disasters. they thought that by praying
and worshipping, the Sun/moon god will be appeased and will bless
their tribe. as people evolved and the worshipping progressed, some
even took it to sacrifising of animals and later humans to appease
the god. Here the concept of god was based on fear, as they are
unable to understand these are not acts of god, but natural
phenomenon.
