FAITH or FEAR

The other day i was thinking about the ORIGIN OF RELIGION/ORIGIN OF GOD, was it FAITH(SHRADDHA) or FEAR.
I believe it to be FEAR, the fear of unknown and transforming that unknown into someone that is known (yet unknown till date) and that known is ALMIGHTY GOD.
If we try to glance centuries ago when human beings were evolving and try to visualize the scenario at that time when man used to wander as nomads and lived in caves or under the trees,
and was fully dependent on nature....

to be contd.
it's already 9:45 pm and i have to drive 24km to home
