(This is lengthy, but gives a totally different perspective on early religions.)
Just for the record, not all people believe in the contemporary and still-very-popular view of Humanity as being only a few thousand years old. Some believe that our current civilization, and those of the past 10,000 years or so (Greece, Rome, Egypt, India), are just the tip of the iceberg. It is just as believable (and far more likely) that Humanity is millions of years old. In fact, much evidence can be presented to support this view.
Nor were we simply a bunch of stupid Neanderthals, and spirituality wasn't limited to so-called `primitive shamanism.' Mystery Traditions maintain that our planet has seen at least two prior civilizations on a large scale, one about a million years ago, called Atlantis, and the other as much as 15+ million years ago, called Lemuria (or Mu). During both of these earlier stages of Humanity there existed what we might call religion.
Lemurian Humanity included the "race of giants" described Biblically, in Norse mythology, and various other religious teachings. The size of the statues on Easter Island gives us a clue as to our proportions during those times, as did the Buddhist statues at Bamian/Bamiyan (Afghanistan) before they were recently destroyed (one was 173ft high, MUCH higher than the Statue of Liberty and the Colossus at Rhodes!). As for specifics of Lemurian religion/spirituality, I'm a little sketchy on details, but Humanity wasn't nearly as intelligent as nowadays, so any religions would presumably have been fairly simple - maybe shamanistic, animistic, pantheistic, etc.
Atlantis, in contrast, saw the rise of religion as we know it, and even though average Humanity wasn't super-intelligent, we could still probably say that the average person was far more in possession of "the facts" as to (the Truth of) religious teachings than is the case today. This position, also, can be supported with various forms of corroborating evidence, and from people the world over, of many different backgrounds and schools of thought! I can say more about that if someone is interested.
Atlanteans, during some portions of their evolution (100s of thousands of years!) were clairvoyant, and early on the wise teachers of our race walked openly among us. We were taught directly and honestly, and fear was not an element of the doctrine of the Lords of the Shining Face. Nor was the acquisition of power or the wrongful manipulation of the forces of nature (living spirits, or lesser angels - as Christians might call them). In our ignorance, however, not as yet possessing greater powers of discernment and wisdom (as if things are any different today!) ... vast portions of Humanity strayed from the moral teachings presented by our Teachers. Through various grave and grievous errors, we allowed our own darker aspects to assume control - and this (influence and control by evil agencies), literally, is what happened. We have yet to recover.
Our karma became heavy, the Divine Teachers were banished from outer expression (but not from Inner Rule), and in several global catastrophes the continent (a vast landmass configuration) of Atlantis gradually sank into the ocean. This occurred 800,000 and 200,000 years ago, and the tail end of that great civilization saw lesser deluges in about 75,000 BC and then finally, in 9564BC. World religions almost universally speak of the flood myth, even though but a fraction of the reality has been preserved or recorded. And the mythical `Garden of Eden' recalls our pre-Atlantean glory (or innocence, rather) ... although this may also suggest our spiritual state collectively before incarnation on this globe (not our first planet, not our last).
Our problem - it seems to me - is that we take so many teachings at face value, or swallow them whole, without questioning. If ancient texts universally speak of something like a `Great Flood,' with figures such as Noah (or Manu) left to represent the portions of Humanity that survived to repopulate our current race ... then may we not draw as a working hypothesis that something like Atlantis did indeed exist, such that maybe fairy tales such as these might begin to make sense? But don't buy into it without questioning it, researching it, and in the end - proving for yourself that such is/was the case. Having done this, I simply retell a snippet as did Plato, although he - a great Initiate - was allowed to tell very little in his time ... and I, neither great nor an Initiate, may only repeat what I have learned indirectly.
Few people recall past lives as far back as Atlantis (and thankfully so!). But of those who do - given special permission in order to better understand the Law of Cause & Effect (taught by Christ, Krishna, the Buddha, Pythagoras, Apollonius of Tyana, etc.) - there is much to reconcile. Religion, or spirituality, takes on a whole new meaning if we find evidence that Humanity has never been without its Guides, and that in fact at one time these Guides walked openly among us, recognized as incarnations of and thus representatives of the One Divinity. Many may find difficulty and resistance even considering this idea, but it won't hurt you.
The truly open-minded may remember (or might learn) that Christ simply means annointed (`Christos,' or chrestos, from the Hebrew mosiach). Likewise `Buddha' signifies awakened, and is not the man's last name. Siddharta Gautama was not the first, nor the last, Buddha, and Christ Jesus was not the first, nor the last, Christ. Shocking to some, but nonetheless true. Look it up, do some soul-searching. This assails no one's personal relationship with Jesus as lord & saviour, except insomuch as it restores to you the right and responsibility to do as the Army says, and Be All That You Can Be. Jesus said the same, a bit like this: "Greater things than this, ye shall do." Buddha also said it, in his last words: "Be a lamp unto your own feet. Work out thy salvation with diligence."
Here are spiritual teachings that did not originate with the Buddha or the Christ, because they were ancient when these men came to re-invigorate and reform them. Yet neither Judaism nor Hinduism were Humanity's first spiritual teachings or religious code, because these were but early presentations for our current world cycle, or age, or civilizations. Dating on the Giza Pyramids and the Sphinx mistakenly place these monuments and temples just a few thousand years BC, but far worse - they label the Pyramids tombs!!! And strangely, not a single mummy has been found within them! Why is that? Hmmm, tomb-robbers, must be. I think not.
More than 200,000 years ago the Great Pyramid was built, and not by simple slave labor (as if that were either possible or simple). The Sphinx is older. Time will show this to be true, although evidence already asserts my crackpot assertion. The research of John Anthony West alone, and Robert Schoch (?), Bauval and Hancock, etc. is increaingly gaining ground and being accepted. Ignorance, bias, fear of ridicule and pure ego keeps mainstream Egyptologists (such as Zahi Hawass) in the dark.
So if the Great Pyramid was built 200,000 years ago as a temple - even after Atlantis' catastrophic decline - then in whose honor? In order that we might recognize and worship What or Whom? When will people gain an inkling of the notion that the Divine is utterly transcendent of all human representations or anthopomorphic conceptions? (Hence the missing capstone atop the Great Pyramid. It never existed!)
Do we not know that it is at once both the greatest blasphemy, yet also the highest form of worship, honor and flatterly to even try and represent the Divine??? How can we reconcile that? I may, personally, be greatly lacking in humility (and knowledge profits a man not one whit when Love is lacking, eh?) ... but for those who yet retain or cultivate this virtue, Consider the lillies. There is your worship, there is your proof of God, there is your religion, dawned upon our globe long before Humanity ever set foot (or consciousness) upon her soil.
And so what if it came from Sirius, via Venus. All will know this in time. The Sphinx guards the secret. And we cannot blast it free with dynamite, or bombs, or filch it from her lips at gunpoint. When we are ready, it will be revealed, willingly and joyfully!
