In 1492, Christopher Columbus landed in what is now the Bahamas, changing the world forever. But was he first non-indigenous person to reach the Americas? Vikings got there before him, and possibly Polynesians too...and those are just the sane theories.
Before we get started on this, I want to make one thing clear - this isn't about who "discovered" the Americas. That, of course, happened somewhere between 13,000 and 40,000 years ago when human beings first traveled from northern Asia to the Americas, probably by boat. It's certain that indigenous people discovered America.
