I like doing these UFO articles as there is always a good technical point to raise against everything that is canvassed. Dr Garry Nolan of Stanford University has said that extra-terrestrial intelligence has visited earth and humans are working on reverse engineering crashed alien space craft. As to the response that if these aliens are so smart how come their space ships crash so much, like drunk drivers, Dr Nolan says that these are drones. But that does not answer the question as the drones should be immune to crashing, as much as they supposedly do.
Yes, people see weird things in the sky, and these are weird craft, but come from Earth, and are no doubt humanly devised experimental craft. As I see it, there is simply no point for some sort of super-advanced civilisation to visit Earth, if they exist at all, which I very much doubt from a Christian perspective, but that’s just my opinion. But, it would make a good book for Amaxon.com, and there is a lot of popular nonsense on this.
