Look at the globe, but not of Europe, but of the whole Earth. If you find a connection between the continents and a land, it would work. Is there water everywhere? So it probably wouldn't work. ALTHOUGH! one was already here walking the water ... but then they crucified it. It is possible that they were ship or aircraft manufacturers. and another problem. the circumference of our ball is about 40,000 km, plus or minus a few stone casts. if you could walk 40 km a day, you could theoretically do it in some 1002 days. However, it would not work for even 20 km a day, not everything is flat as the sea level, there are also some hills and dimples. and when the wind blows at sea, one step forward, two backwards ... Forget and do something else.
