To make some observations relative to some of the propositions advanced in the OP, let me make the following comments:
First, there is absolutely no doubt that superstition did play an element in the evolution of the various belief systems of humanity. Just as children learn that the wrath of a parent or other adult is fearsome, but that said parent/adult can be propitiated by behavior in accordance with parental commands, gifts, and gestures of love and affection, so, no doubt, people, conditioned by their childhood experiences, attributed to the volcano or the thunderhead the characteristics of those fearsome adults which they had learned to deal with as children. And, of course, they did have practical grounds for thinking so: they experimented, and it worked. If, every year, they sacrificed a virgin* to the great god Ghu who lived in the volcano, He would not cause it to erupt … except sometimes, when it was clear that Ug, the outcast who was known not to live by the Rules of the Tribe, must have sinned so badly that Ghu was wrathful nonetheless. Or perhaps the sacrificial maiden was not virgo intacta; no God wants some man’s leftovers, after all!
However, to attribute all religious experience to this sort of superstition is a false generalization. Many people, from Akhnaten and Moses down to many living people, have experienced some sort of theophany in their lives. Some of this can be attributed to hallucination and desire to believe, but not all. I subjected my own personal conversion experience to skeptical analysis, and infer that without a remarkable degree of subconscious precognitive ability, along with a perverse subconscious desire to rid myself of rationalism, the only reasonable explanation of what happened to me was that I had an experience of God. And typically, conversion experiences tend to have a number of characteristics in common which are not even so easily explained as Lekatt’s NDEs, except on the presumption that an actual theophanic experience in fact happened to those who undergo them.
Does this necessarily prove out anyone’s theology, validate any particular religious system? Perhaps not. If there is a God worthy of our belief (as I believe there is), one assertion that can be made of Him is that He is greater than, impossible to encapsule by, human descriptions and categories. The Sh’ma, the Hijma, and the “negative assertion” of the Tao are all true of Him. As J.B. Phillips entitled one of his books, “Your God is too small.”
But, raised in a Christian culture and with a quasi-Christian parentage and upbringing, one of the things I discovered about the God Who had revealed Himself to Me is that He corresponded quite clearly to the character of the God Whom Jesus taught and Whom He called Father. This is not, be it noted clearly, the divine megalomaniac with a prejudice against sex and human happiness preached by some brands of Christianity who seem to have jumped directly from Leviticus and Obadiah to Romans, with more interest in learning the rules to propitiate Him than in finding out what behavior He actually wants, as taught by the Person they agree is His Son.
By the way, the idea that Jesus was not a man like other men is itself a Christian heresy, Docetism. Traditional Trinitarian theology claims Him to be the Second Person of the Trinity, the Word of God, incarnate as a human being, the sole real case of what Hindu thought calls avatars, truly God and truly Man. There are a lot of supposed Trinitarian Christians around who have placed Him on so high a pedestal that they fail to recognize their own Docetism, but sound theology agrees with the strongest of agnostics in saying that whatever else He may or may not have been, Jesus was a man.
A particularly petty point that is sufficiently irksome to me to be worth making is the misspellings in the argument. Mohandas Karamchand Gandhi was perhaps the foremost teacher of satyagraha, the nonviolent protest which Martin Luther King Jr. Also taught. If there was a famous religious leader named Ghandi, I am not aware of one. Likewise, the title of the Tim Allen movie was a pun based on the homonymy of the term for a single item in a contract with the second half of the name given the legendary figure created by the assimilation of St. Nicholas of Myra into the Father Winter mythos of northern and eastern Europe. There is no E in Santa Claus.
Finally, the scholarship of Charles Darwin has no impact, except to strengthen it, on the faith of the majority of Christians. He is seen as a threat to their beliefs only by a minority who practice a naive literalism with regard to the myth, in the Campbellian sense, used to describe Creation, and who, in consequence, cannot accept the idea of an intricacy of creation that might bring forth humanity, not by an anthropomorphic deity gathering together dust, but through the implementation of a system that is profligate in calling forth eurypterids, arthrodires, dromaeosaurs, uintatheres, mastodons, and australopithecenes. A Someone who is capable of seeing not only every sparrow fall, but also every pterosaur, who not only garbs in glory the lilies of the field but the tree ferns and giant horsetails, is larger and more complex than their conception of a wrathful tyrant, a Daddy who will cast down and out to eternal torture if one does not convince Him that one is sorry for one’s misbehavior.
Hence my assertion is that the OP works only by grouping into superstition not merely some but all religious experience, throwing Julian of Norwich and Pierre Teilhard de Chardin into the same pot with cargo cultism, and argues against a brand of Christianity which is advocated only by a noisy minority of that religion’s adherents.
