Just remember, intelligent does not always mean friendly.
After following the UFO phenomena all my lifetime, I'd have to say that I think there may be something to it. Too many sightings and events have happened that leave the door wide open to speculate that extra-normal events have happened and are not able to be explained away. If we are being observed by other beings from elsewhere, it is most interesting to me that they have been as benign as they have towards us. Most encounters that I have read about leave an impression that we are just a curiosity to them and not worthy of their engagement ~ either productively or destructively. It seems as tho the Earth is like an aquarium experience for them. Who knows, perhaps that is how our planet and we humans are billed throughout the galaxy? Like a Disneyland attraction.
Since long ago reading Von Daniken's books about the images on the plains of Nazca in south america, I have speculated that someone might have been having fun drawing them from on high with their version of a laser cannon, just for kicks. Somehow, I have been left with an impression that our visitors from outer space do not take us as seriously as we do them. Doesn't mean I think they are a figment of our imagination, just that we are perhaps seen by them as not worthy of cross cultural engagement ~ yet.
And yes, Chuck, I do think I saw something extra normal back in 1961 in NC. I couldn't/can't explain it within the circumstances in which it occurred, but it was definitely memorable.
