UFO's are mentioned in the bible; it's not like its anything new.
Jacob's Ladder was the "bridge between heaven and earth". Jacob went aboard the spaceship; he walked the stairway to heaven.
Jacob agreed to the genetic changes and thus the twelve tribes started with his sons.
Another validation of this is when he wrestled with the angel and was struck in the thigh. This "wrestling" was not a physical thing. It was oral discourse. "Thigh" is often used as a delicate reference to sexual reproduction..."fruit of loins". His being struck in thigh is hint of genetic mutation. His lameness is metaphor for "stumbling". Actually, the whole of humanity took a great fall when Jacob agreed to this.
Jacob learned a bit about genetics and was excellent breeder. He learned animal husbandry from these wicked angels. this is evident in the way he bred stronger stock for himself out of his fil's herd.
The wicked watcher angels have been abducting people to carry out genetic experiments. They were created before us and they are resentful because we are "newer models". One thing they have done is to alter our genetics toward being overly aggressive.
