I have heard alot of this before. And since my father (brilliant man I might add) taught me many wise lessons I believe we are not alone and off world probably means off world. Dad always told me if it was in the realm of imagination it was in the realm of possibilities. He was never a dreamer but a staunch no nonsense republican. So don't even try to say he sounded like a liberal. He has been gone for 51 years most stuff today was only in someone's imagination back then.
