Or it would give Hispanics more claim to the whole US. 
Funny, who were the first to make cloth into sheets to sail? I taught myself how to tack and sail against the wind in a small Sail Fish 30 years ago. this leads to interest on how the boats of sail moved about the oceans.
Were the first sails made of woven cloth or perhaps tree bark pounded very thin, Someone got the idea 20,000 years ago on how to use wind power, and when the center board came in and or a skeg is interesting.
Stone age people had the same brain we have today and there had to be many who were interested in the problems of their day, and invented new solutions.
To move against the wind and tide to fish or trade up coast the imaginations of many is not so strange for those in the past. So they only had stone age tools, seems that they managed to put them to good use and travel the seas.
Weather was a problem and in a good blow boats were sent way off course, new Islands and Continents they ran aground on.
Turn history upside down, say the people before Egypt found South America and learned stone masonry from them. They returned home on a fair breeze and instructed the building of the Spinx and Grand Pyramid.
Tropical climate at that time and as the weather changed into desert the people left and the Egyptins moved in to a land of sand and these remarkable momunites. So they tried to duplicate the Pyramid and failed what 5 times.
They found enough of the former civilization to begin to copy their head gear, rebuild their temples and claim them as their own.
Jack Horner the Archaeologist has demonstrated that the Spinx had weathered for a thousand years from water run off before the desert took over.
The seas have fascinated humans for as long as we saw them. We find a way to sail them over and under, off to new lands and unexplored places. To believe North and South America was FOUND by humans only 10,000 years ago is absurd.
Perhaps it was The reverse, the wind blows west to east could be our Continent found Europe. Perhaps the story of Atlantis referred to our continent. We did not sink under the sea, something caused us to get lost from the minds of the Europeans.
I love to speculate on this stuff, some of it is as far out as Alians coming to earth, but, darn there are so many mysteries of the past, what fun to wonder.
