Almost anyone who at the time knew something about navigation. First the Portuguese had - even before he started out - worked out that Columbus could never find China where he thought it would be; and later on the Spanish experts decided the same thing, but Queen Isabella decided to let him have a shot at it anyway.
Most famously, the cartographer (not explorer, by the way) Amerigo Vespucci also worked out that what Columbus had found could not possibly be China. He never called it "America" himself though, nor did the people around him. The very first mention of "America" is on a map made in Bristol, England, showing the parts of North America that had been discovered by an expedition funded by a British tradesman called Richard Ameryk.
The explorer who stayed home was Prince Henry when he taught sailors in navigation to make sure they make their way through their destination to find a water route to the indies (Asia). They wanted to find a water route because the land route in Constantinople was closed off.

Christopher Columbus.
A lot of people think it was Christopher Columbus but it was really Leif Ericson who was the first European to reach the New World. He was a Viking explorer and it is not known when he landed but he set out in 1003 and later returned back to Europe.
He claimed San Salvador for Spain. Columbus believed he had reached Asia and was in the Indies. This belief explains why he called the people Indians. (5th grade history book)
He concluded that the land discovered was larger than previously believed, and different from the Asia described by Ptolemy and Marco Polo and therefore was an entirely new continent
Though Columbus was probably not the first European explorer to reach the Americas, Never admitting that he had reached a continent previously unknown In either case, Columbus left Portugal for Castile in 1485.
