There is always a tip of the hat to the Mariner that convinced OTHERS to leave their tiny seaside village and venture ‘off the edge’.
The first person to do ANYTHING that no one else had knowingly done before (That is why they are called the first).
Don’t forget the aliens from the 1950s that landed here will have a great shock when they return.
For example....
If you were an alien and saw a person walking a dog, dog takes a dump and the person holding the dogs leash cleans it up.
Who would a normal alien think is in charge? AND the earlier ones would have noted the two legged ones were in ‘charge’.
There is no “edge” but a circular wall of ice, which Magellan just followed, so they say.
I find all of this stuff very curious. I don’t believe the earth is flat, but I don’t disbelieve it, either.It’s weird.
