Obviously the SETI community is unwilling to spend any time reviewing the enormous amount of evidence that aliens have been visiting Earth for at least many decades if not millennia. Super sentients: YES! Aliens: NO! is the motto here. It is clear from their books (which I have read) and their articles and lectures which I have reviewed, that they essentially never review the UFO evidence such as the 5 large scale scientific studies, the many multiple witness radar visual cases, the physical trace cases involving reports not only of flying saucers on the ground, but the 15% of those cases involving reports of humanoids.They know nothing about national security. They also are unwilling to review the evidence of abductions. I can find no reason to accept proclamations from radio astronomers about the behavior of aliens, no less earthlings. Of course the reason is obvious. There is no need for listening for primitive signals from out there using technology compatible with ours.If aliens are visiting, as they surely are, SETI which is looking for signals not looking for aliens, is out of business. They are truly getting desperate. The collective rule is "Don't bother us with the facts,our minds are made up." How pathetic and irrational. Stan Friedman Listen to 'Strange Days...
