So what’s your take on those things the Navy has been chasing around for the last 15 years or so?
Earth has been broadcasting in analog for over 115 years and digitally for over 50. Given that there are billions of galaxies, statistically there is a good likelyhood that advanced alien civilizations exist. However they are too far away to physically visit us or us them. However they know much about earth and its atmosphere. Suppoose they transmitted signals that used earth’s atmosphere as a giant video screen. Well programmed messages couls “recreate” all sorts of rapidlymoving, suddenly disappearing images that pilots observe and are puzzled. Some of the programs may oranize the “screen” to form cloud like images that radar may actually record. anyway that is what I think is happening when “UFOs” are being observed. BTW there may be a whole string of alien civilizations linked by such radio communications and perhaps one day our computers may receive some very interesting and unusual communications to link us with other civilizations.
