DID THE INDIANS SEE COLUMBUS?

I have participated in discussions regarding the inability to see something that was right in front of me. Case in point, the indigenous people that stood on the beach and watched Columbus row ashore might not be able to see the ships anchored just off shore because they had no concept of a large ship with cloth sails. I saw a movie recently that talked about that same issue. The name of the movie is "“What the #$*! Do We Know:”. While it may seem ridiculous that an object so large couldn't be seen by the people on the beach, I can testify that in the last few years I have experienced the same thing. If I'm looking for something and I have a mental picture of it, I can be looking right at the object of my search and not see it because it didn't fit my holograph. Sooo...maybe there is something to all that. I did see this ship just off the coast of southern California near Morro Bay.
