Several days in a row we sighted groups of metallic, saucer-shaped vehicles at great altitudes over the base Germany, 1951 and we tried to get close to them, but they were able to change direction faster than our fighters. I do believe UFOs exist and that the truly unexplained ones are from some other technically advanced civilization.
Statistically it's a certainty there are hugely advanced civilizations, intelligences, life forms out there. I believe they're so advanced they're even doing interstellar travel. I believe it's possible they even came here.
The statistics of life out there and the statistics of intelligent beings and advanced civilization is a certainty, the way I look at it. It has not been accepted, because we've been in an anthropocentric era.
I think we overrate ourselves in terms of our abilities and capacities. I mean, just because you can build a really swell bridge doesn't, to my way of thinking, mean that you're an advanced civilization.
It's worth remembering that all technology leaves a footprint. For example, our own technology is leaving a footprint in terms of global warming, which could be detected from a long way away. One assumes that a very advanced civilization that has been around maybe millions and millions of years would have an even bigger footprint that might extend beyond its planet to its immediate astronomical environment.
Lying under an acacia tree with the sound of the dawn around me, I realized more clearly the facts that man should never overlook: that the construction of an airplane, for instance, is simple when compared [with] a bird; that airplanes depend on an advanced civilization, and that were civilization is most advanced, few birds exist. I realized that If I had to choose, I would rather have birds than airplanes.
