So it is your opinion that the official history of our planet and all the events that have happend on earth are all accurately recorded? There are are no hidden/occult/secret/alternative histories? Because it would take too many people to cover up anything that would be on a grand scale? I'm not sure how many conspirators it would take to cover up the events you proposed. My guess is that it would not be thousands as you say. How many conspirators do you think it took to create a fake religion called Christiany and keep it a relative secret for 2,000 years?
