You really need to be nicer to people here or you will probably get banned by someone sooner or later. People are trying to get away from the reddit atmosphere here. Don't act all superior because you spotted a mistake. That's really childish.
Dude, delete it and try to forget, nobody is buying your excuse. You called someone dumb for making a mistake, despite it being you who made the error while OP was bang right.
It's very embarrassing mate, you can try to style it out all you want and a couple 10 yr olds might buy it but not much more than that.
Personally I think you'd do best deleting the comment and trying to forget that you were just that stupid once upon a time :) x
Wait, you're saying that the Aztec empire was just 64 years old when Columbus discovered America and ships with conquistadors followed to butcher and enslave everyone?
There were people there prior to the Aztec empire conquering them. The Aztec empire is just a specific government that ruled the area at that specific time.
The Napoleonic empire, for comparison, only lasted 1804-1815 (with a hole in the middle).
