Well... 1. You clearly know nothing about the difference in character between navigating the Atlantic and navigating the Pacific (though you might take a hint from the latter's name). 2. The Polynesians are not known (afaik) to have made trips of the size of crossing the Atlantic non-stop. 3. You cannot do what either did so maybe you should have some humility before criticizing the abilities of historical figures who exceed your abilities.
As I said - when you've done the same then you can say there was nothing to it.
