Call me barking, if you like, but I have a deep-rooted suspicion that someday soon, a discovery is going to be made which will cause the whole of humanity to stop and re-think not only the course of human history, but our very place in the Universe. What could such a discovery consist of you ponder? Well, there are indeed many fabled wonders, which believe in their existence or not, you can be rest assured that there are those out there seriously seeking them.
The sort of thing which might fall into this category would be, for intance, the tomb of Osiris, or perhaps the Hall of Records, the Cavern of the Ancients, call it what you will, or alien visitation in prehistoric times. Anyone with an open-mind can accept the possibility of any sort of dicovery taking place. The real question is, would the public ever know if it such a discovery was made? That's debatable, but let's consider the possibility for a moment, that someone, somehow discovered the tomb of Osiris, complete with 12 foot tall skeleton, after all "There were giants in those days!" The Egyptian King Lists tell us that Osiris existed, so why not? If Schliemann or Evans hadn't taken supposed mythology at face value, then perhaps Troy and Knossos would never have been discovered.
We live in a sceptical age, when sagas and legends from the past are dismissed as fantasy out of hand. However, the evidence has always tended to suggest that the opposite is true. Supposed myths when regarded in all seriousness, can probably be proven if the requisite evidence has survived the course of time. You can't disprove a myth, neither through lack of evidence or by reasoning alone. Reason tells us that giant men or aliens, with long lost powers and abilities, couldnt possibly have held sway over the Earth in ancient times, but that doesn't mean that they didn't. Anything's plausible and logic would suggest that at least one myth which is currently regarded as impossible, must be based on real events! Which one will it be?
