UFOs and the ROMAN EMPIRE

We know now from modern science that the Biblical statement: "There are more stars in the heavens than grains of sand on Earth," is true. In the untold trillions of light years across the Universe, it is a mathematical certainty then that there are civilizations on planets out there that far eclipse the technology developed now on Earth. Have beings from Outer Space, other than God's Angels, been visiting Earth with an agenda for centuries? The Bible tells us that Earth is already the watery prison planet of the fallen angels, Satan's horde.
