Before the West declared themselves the great scientists of the earth, before their own Renaissance, Muslims already were making discoveries in science that took the West hundreds of years to even begin to imagine. What a shame that people in Europe were being persecuted by the Church for their suppositions that the earth was round; they should have come to the Islamic world--- an Afghan Muslim had proved that in 793 C.E.!
However, the studying of the universe brought forth more questions, and more curiosity. The Muslims in West Africa were so intrigued by what was on the other side of the Great Sea, that they began their expeditions into the great unknown. Early reports of these travels are sketchy, but we can be sure that they crossed the Atlantic by 889 C.E.
That was 603 years before Columbus. And that is not counting the actual physical evidence in the United States today that dates back even further; however, we do know, as De Lacy O'Leary pointed out, that Muslims definitely had the scientific knowledge and skill to make journeys across the Atlantic ocean.
We were in the Americas, hundreds of years before Columbus, and of that we can be sure.
Did Chinese sailors, led by a Chinese Muslim admiral named Zheng He, really discover America before Columbus?
