I remember at a District Convention in Yankee Stadium back in the 80's where the District Overseer mentioned the possibility of one day being able to share the universe "with other creations of Jehovah" as he put it. It definitely got everyone's attention because he even went so far as to say that perhaps UFOs are a creation of Jehovah, but we haven't been told of their purpose. When I heard that I nearly choked on my JW-hoagie.
But since then, when I watch a documentary on The Discovery Channel it always makes me wonder what was God thinking when he created things like dinosaurs? Will we ever get to see them return and share a world with them? What about UFOs? Is it possible that God has created other creatures of equal importance as humans?
