The Asians that 'discovered' America are what we today call native Americans and have left an extensive history as their evidence of 'discovering' this land. Not only in the oral history but also in structures and sites that are so old that they are not even associated with the peoples that inhabited the Americas during the near simultaneous 'discoveries' by the modern Asians, Eurpoeans, Norse, and perhaps others. But as far as who got here first in more modern times it was most likely the Norse or Asians as oppsed to the Europeans
The Americas were discovered by humans and when this first discovery actually occurred is debatable. It is now known that humans appear to have existed in North America as far back as 40,000 years ago. The origin of these humans could have come from many directions. One possibility is by way of a European boating people, who traveled along the edge of the Atlantic bordering polar ice sheets. The same as is the travel methodology of the Eskimos. Or reached by an out of Asia people who did the very same thing.
There are even indications that the Polynesians reached the western coasts of both continents. The Polynesians are considered a polyglot or mixture of several other ethnic groups. It is possible that the Polynesians may have even originated from India. So in some ironic sense, the Americas may have once also been reached by "Indians" long before Lief Erickson or before the misnomer accidentally applied to the native peoples of the Western Hemisphere by a confused Christopher Columbus.
It also quite feasible that whomever the first humans who settled the Americas were, they may have also been the first humans to discover and reach Atlantis. It would be unbelievably ironic if all the civilizations, that have come into existence since Atlantis sank into the sea 12,000 years ago; were actually promulgated by the influence of these first "Americans." In other words the people, who first discovered and settled the Americas may have been the progenitors, via Atlantis, of every civilization that came to exist after 10,000 BCE. Now wouldn't that be a disturbing revelation?
