The Spainish sailors own accounts disprove this

When we saw so many cities and villages built in the water and other great towns on dry land we were amazed and said that it was like the enchantments (...) on account of the great towers and cues and buildings rising from the water, and all built of masonry. And some of our soldiers even asked whether the things that we saw were not a dream? (...) I do not know how to describe it, seeing things as we did that had never been heard of or seen before, not even dreamed about.
