Yes, there is undoubtedly much we do not understand about history. But you'd have a hard time convincing me that the Bible is a sound place to look. Yes, there may be events in there that have been misinterpreted, but you're far more likely to decrease the accuracy of your history if you take a conspiracy seriously.
@1814: "Why Sam? If you believe in Angels, you are believing in things not of this earth and hence, alien." Because using a 3500 to prove something is a poor attempt at doing so. The bible is the claim of events, but not the evidence. Hard, objective evidence out weights a collection of desert scribes which are cherry picked and interpretation based on the readers taste. And I do not believe in angles, demons, and other supernatural superstitions.
You can literally look up many claims that museums are actively covering up many things. Really think about it. Say you found something that totally blows away what we conceive to be the "truth" about history. Do you think you legitimately have a chance to get that knowledge to the public? But I think we should use our common sense. Whales do not swallow people. Chariots do not go into the sky. Now are those people liars? I don't think so. I believe they were trying to explain something they did not have words for.
