One of the points of Archaeology is to check the historic record. I will point out the Tuscon Garbage Project as an example. It plainly shows that what even honest people say and what they do ain't the same thing.
Also, more importantly, what people think happened, and that is what they record, and what really happened doesn't need to coincide.
For example at Mos Espa the history 10,000 years from now will show that this was a famous ritual space where the hero/demon Vader was born. But an Archaeological analysis will not find a community. They will find buildings that only make sense from a certain angle, are unique, just look like they work, but don't. There will be small temporary habitation that is concurrent with the time period. This will question the historical validity of the Hero/Demon Vader, but will be suppressed. The truth that Saint Luke, the companion of Christos, redeemed his father with the Force of Holy Ghost as given by Christos is undeniable. Those future Archaeologists will have to weigh the importance of their findings that Mos Espa was a theatrical film set, versus the fury of the inquisition.
