The fallen angels are still within the realm of these laws but now are in a disruptive mode due to the fall and expulsion from heaven.

In the same way we as humans have fallen and developed, I think other beings of God's creations have gone a similar way.

Why are animal mutilations occurring where the reproductive tissues of female animals are removed with astonishing precision with sightings and evidence of UFO's in the area? Why would they need this stuff?
