assuming that aliens do exist and that they are advanced enough to have invented interstellar space travel, the following possibilities must be true: a) they can fly between stars but have not yet discovered earth or: b) they have discovered earth but for some reason have decided not to make themselves known to us. if a) is true, then we must sit and wait until we are discovered, it seems pointless to try and initiate contact on on our own. if b) is true then aliens are indeed aware of our existence. who knows why they are still hiding themselves from us... anything is possible. obviously we are powerless to force them to reveal themselves. and anyway, science has never been based on pointless speculation which is what prof. loebs theory amounts to.
