God's Universe is essentially infinite. It is countless trillions of light years across. That means that it is a mathematical certainty that there are corporal beings in other solar systems that are light years ahead of us technologically. Maybe, they have been visiting Earth and "helping" us for centuries of Earth time. We certainly need all the help that we can get.
Maybe, they helped Christopher Columbus and his crews on their historic discovery voyage in 1492. Logs of that voyage mention strange sightings and flying objects. And, remember, they were crossing the mighty Atlantic in three wooden boats during hurricane season. UFOs in 1492 is the Paranormal, sci-fi, althernative-history tale of that voyage.
