Saw an interesting comment about how archaeologists have learned that the layers they dig through are not always nice neat and clean, and how you can actually end up with one older era folding over a younger one and muddling things. I forget his exact words, but it was something like "Due to this, I live in fear that in 2000 years, some poor expert will be going 'They had based their religion chiefly on a Heyzeus Christ, who they thought to have died on a Hashtag for their sins'"
