The humble, materialistic origins of God

I do not agree with the idea of a God. Especially, the prevailing one, which puts it as something to do with fear of the unknown. (An unknown can cause fear only when it is linked to a known. e.g. We are afraid of heights only because we know it is painful to fall) Our ancestors too would have been right thinking people like us, who looks for a reason to do things. 

It is probable that our early forefathers found, the unknowns increasing at a much faster rate than the knowns. Since, as it is very well known to us now, the more one knows, the more unknowns, one knows. But, instead of reaching the obvious conclusion, that there always will be something left to know, they took to the unnatural maxim, 'There are many things beyond human comprehension'. Why?

I think they were looking for an excuse to escape from the drudgery of learning. Choosing the former reasoning would have entailed further study. As it is nowadays, if the proliferation of educational aids is anything to go by, in the old times too, learning would have been a pain. And the initial, natural reaction of the suffering many would have been to think of creating hurdles in the activity of learning. Like coming up with imaginative excuses for staying away from study, declaring the idea of learning itself as a misplaced, unnecessary, or useless one, like we do these days to wriggle out of things uncomfortable. Here, a really good, intelligent and effective response would have been to declare the very outcome of learning, that is, understanding the nature of things itself, as something beyond human comprehension. Sure, it would have worked well, but with a danger. A question could have come up, who then can understand it?

This would have been the time, when the concept of a superior entity dawned on them. Where the entity itself is beyond comprehension, whatever be the current levels of contemplation. An image with infinite powers. To their delight, this idea continued to serve them well, ever after. The idea could successfully stonewall, delay, or justify, anything one found inconvenient to face, handle or do, making it an essential for life. And a new activity is born, spiritual quest, which helps us by successfully replacing each object of reference, by the time it loses its novelty. 

(Incorporating such ideas into daily life would have been needing extensive manipulation of data, and unique objects of reference that remained so. This is where they found useful tools in stuff like heavenly bodies. https://hubpages.com/education/Rational-Mythology )

Over time, from the earliest images of unknowns, this would have further metamorphosed into singular shapes, unusual animals, magnificent entities, and finally to abstract ideas.
