Their “re-creation” was missing something…Oh yeah, a crew of actual Vikings. Just because we’re more technologically advanced doesn’t mean we’re automatically better at managing ancient technology. For example, we have no clue how to build a pyramid on the scale of the Egyptian pyramids.
“Institutional knowledge” makes a big difference.
Plenty of Vikings sank too. The ocean is mean. And we can totally build a pyramid, the only challenge we’d have is getting the funding and permits. Outside of that it’s just moving rocks, we can move rocks real good.
