re: 1907 Vancouver Canada -- in Color VFX 60fps Remastered -- Population, 1901: 26,000 (?!?)

There’s really only four possible answers:
1. They didn’t build it, but found it and renovated it.

2. They didn’t build it, but conquered it from a previously existing civilization and erased the records of said conquest/genocide.

3. They did build it, but did so significantly earlier, and the census numbers are wrong.

4. The built it exactly how and when they said they did. The only reason anyone thinks this is strange is because our current day governments have so over-regulated and zoned society that it is now impossible to replicate these things.
