Though the image is grainy and somewhat difficult to see because it was shot with a trail camera at night, the outline of the deer's head as well as what looks like two bright lights in the sky can definitely be seen (see photo).
This occurred as scientists are debating the possibility of intelligent life on other worlds. We now know that planets definitely exist circling other suns, and it seems probably that the basic building blocks for life appear to be common throughout the universe. It therefore seems a little arrogant to presume that we are the only intelligent species.
But are we really the only intelligent species, even here on earth? There must have been a reason that the UFO, if that's what it really was, attempted to make first contact with a deer in Mississippi rather than, say, landing on the front lawn of the White House, as the spaceship did in the movie The Day The Earth Stood Still, or at the United Nations. One can only assume that our extra-terrestrial visitors had been monitoring our radio transmissions and world events for some time. Perhaps in doing so they concluded that the deer must be the most intelligent species on earth, because it obviously couldn't be human beings.
Of course, this is just speculation. The aliens, if that's what they were, have probably long gone back to their home world, and the deer isn't talking.
