Crete was inhabited by Ancient Greek speakers, their ships never ventured farther than the Mediterranean . They saw the height of their power in the very late Bronze Age . The eruption of Santorini and the ensuing tsunami wiped out their culture, giving rise most likely to the myth of Atlantis. The ships of the time were costal water vessels and the while they could navigate by sun and stars, that would only give them approximate latitude, they could not determine longitude, so by necessity they sailed primarily with land in sight. The Med was fairly well mapped and well known to ancient seafarers, so making a direct route across, ie north to south was possible, because they knew at some point they would have landfall and then could determine exactly where they were. Without the ability to determine longitude sailing from the Med across the Atlantic would have been a hit and miss affair, with a very big miss. The other point to bear in mind is that the ancient Greeks, Egyptians and Phoenicians had mapped the world as they knew it and the Americas don't show up anywhere, the African coast shows up, because they were able to sail around it, always keeping land in sight.
Rocks with incised markings (petroglyphs) are hard to put an age to, it can be done with some certainty depending on the mineralology of the rock and so far all these rocks found in the North Americas have proven to have been incised no earlier than the 18th to 19th century. There are of course Native American petroglyphs and these have been dated on occasion to show considerable age, but they are few and far between. To date there is no archaeological evidence of any sort to show that ancient Greeks, Egyptians or Romans ever reached the Americas, there is even scant evidence that the Norsemen made it to the mainland of Canada and whatever way you look at it visits by these people would leave evidence of some sort.
If America wants ancient history then she should look to her own indigenous people's, not invent unsubstantiated histories of visits by people's of the old world, had the time and effort been taken to study the Native Americans before their culture was wiped out by the relentless push of the so called civilised white man, we would have a much clearer understanding of the Paleolithic and Neolithic cultures of Europe, because that essentially was the cultural level of the Natives at the time.
