Many people have scoffed at the idea of beings from another universe visiting earth. But in 1970 we witnessed the drama of a crippled American spacecraft being brought back to earth.

How would that planet's inhabitants remember our men in myth and art? The answers we could give fit exactly the vast number of unexplained mysteries that have been found around the world.
