If God exists then why so many religions have bitten dust since organised praying took roots? Also, inspite of so many religions met up with extinction still why around 4000 religious faith still exists
I am completely perplexed
The tendency to form superstitions is innately semi-"hardwired" into our psyche, and is an artifact of our mind's propensity to make sense of the world around us from scratch inorder to improve our chances of survival. And this tendency is not limited to humans. It can be observed in all creatues capable of learning, ours is merely more highly developed in keeping with our greater intelect. The good news is we can also learn to ignore it.
I think the fact that there are so many religions is proof in and of itself that it's all made up. If there were only one true god defined by one true religion then there wouldn't be all this room to just make up other gods and other belief systems to suit your preferences.
God works just like Santa Claus does: many people around the world have a Santa Claus myth but each is defined by the culture of its place of origin. For instance, the Norwegian Santa Claus isn't the same as the American Santa Claus nor is the Spanish Santa Claus the same as the Arabian Santa Claus. Since Santa Claus isn't a real person, everyone is free to make up their version of who he is and what traditions are attached to each country's version. If Santa were real, we'd all know the same things about him and be embracing similar traditions regardless of whatever country we're from.
God works in exactly the same way -- people make up their version of him and what he thinks, wants or expects of us based on the preferences of those who created the religion and those who choose to follow it.
We can guess at why many religions have disappeared. I am inclined to think that it may be due a number of factors. The appearance of a charismatic preacher, a new version of a religion or a new religion superseded in popularity. A superficial desire to be different seems to characterize many religions today, essentially, the same product repackaged.
The continuation of religious faith persists because an afterlife rests on two false notions. Firstly, a notion of a reward and secondly a notion of continuity. The promised reward is contingent upon living in accord with religious precepts/prescriptions.
The notion of continuity is limited only by the imagination of the believer in which he or she each settles for a comfortable image. I doubt that beyond the realm of imagination that there is an afterlife because when dead there is no you nor I nor anywhere to go.
