History is the hardest of all knowledge to hold on to. People record history with cultural bias and utilize descriptions crippled by the limited scientific knowledge of the current time. People hide disgraceful or shameful events so that future generations will never know of them. History is easily lost. Science and technology are used every day and improved upon from generation to generation, thus making it harder to lose the knowledge. History only records events. And when records are changed or destroyed, when the people living in the current time have long since gone and the history they knew never passed on to their progeny's progeny, history is forever lost, changed, or willfully ignored.
History has also been hampered by the ability to keep records safe. And those records that do survive can only be read through translations which can never perfect or bring forward the true, exact meaning or intentions of the writing. Much guesswork and supposition will be inherent in the translations of these documents, especially in cases where the transcriber of the recorded event did not have the words to describe that which he was witnessing. This leads to the writer tending toward the use of metaphor, simile, or his own assumptions and guesses and naive perceptions of events. Science and technology do not tend to have this problem. Even if advanced methods of doing something are lost for some time, they can always be rediscovered because math and science are not specific to culture, language, or time.
In this day and age, we have so many people meticulously writing about any current event that future generations will have the opposite problem. They'll have many differing accounts and opinions to wade through to try to get to the heart of the matter. But at least they should know what was happening to a greater degree than we have today of far past civilizations. Which is sort of what I was thinking about.
Most people would think it silly and unbelievable to think that aliens have ever actually visited out planet. But how would we really know when ancient South American Civilizations described the Spanish as Gods? How much myth and how much religion was created whole-cloth from the imagination in order to answer spiritual and metaphysical questions plaguing ancient people? And how much of it could be historic observations of alien civilizations visiting our planet during civilizations infancy?
Could not the idea of Angels have come about as the only way ancient man could conceive of humanoid beings who fly through space? The wings would be the artistic metaphor to show that these beings could fly and that they came from the sky as opposed to men who actually had wings. Could not creation myths and stories of Gods have come from beings who showed such strength and power and marvelous tools that the simple minds of earth's inhabitants had no way of describing exactly what they were seeing?
Could the idea of an end of the world conflict in which the divine creator comes done from the heavens to save the righteous and slay the wicked be a promise and not a prediction? What if alien beings had foretold that they would be watching and they would save the people of Earth if they ever grew to bring about their own destruction? Wouldn't that mean that the hastening of another world war (as many fundamentalist Christians and Muslims might see as a good thing) not bring about the descending of higher beings to the earth because it is predicted but because they promised to come if things ever got so out of hand that mankind was about to destroy itself?
What would be interesting is that this concept, over time, of a promise to help had become, to Man, a prophecy that will eventually come true. In this case, some might seek to hurry it along since they see no hope that it will never happen. And yet looked at in the view of a promise to help if things got that bad, we would see that we don't ever need to get to that point.
Perhaps all of the Egyptian mythology, if written with the scientific knowledge and technological language we have today, would become clear and understandable as something real and material instead of metaphorical and spiritual. Perhaps the Norse Myths are just telling the same stories but through their own cultural bias, environmental settings, and Nordic language. Maybe all ancient civilizations were visited by the same people but could only tell the tale in the only way they knew how.
Or perhaps all religious texts and creation myths, stories of Gods and ancient heroes, are all just stories.
