The article doesn't say how exactly how old the ships are, but seems to imply that are contemporary with riverboats going back to 2,500 bc.THE oldest known remains of seafaring ships have been identified in a series of cave stores on the Red Sea coast of Egypt.
Obviously such a well- developed system took a long time to
achieve, meaning there were even older boats. So...could they have sailed to the Americas?
