Everything makes so much more sense now...thank you, Johnny Q! I have photos of a building with Roman Numerals across the facade, originally late 800s (can't remember exact number or find the photos in my computer) then changed by adding an M to late 1800s. Guessing now that it may have happened many times...

This also fits in with a "reset" somewhere in the alleged mid-1800's (?) with photos of empty cities (as seen in videos like "The Lost History of Flat Earth" by Ewaranon) which were apparently followed by orphan trains and a series of World's Fairs for which elaborate, ornate structures were supposedly built, only to be demolished. Amazing "new" technologies were also "revealed" at these events and then apparently suppressed?
