(Such propaganda is not just used by the military, political and religious factions use it and those that fit neither category (Cult groups) and since our world is filled full of so many jokers in the pack I tend not to jump to conclusions about something being "alien in origin".)
Wise, or simply just good old 'common sense' there Stryderunknown!
However I do wish you'd stop reffering to the possibility of ET visits as 'psuedoscience'.
I acknowledge the fact that the evidence for such visits, is at best best poor so far, but our current knowledge of science indicates that we should by now have been visited by, at the very least, unmanned probes. If this is not the case, as I've stated before, then there has to be a good reason for it. Either the evolution of an intelligent race is extremely rare in this universe (unlikely), or the long-term survival of such a race is very difficult to accomplish (much more likely). Either way, the possibility is far from being within the realms of 'psuedoscience'.
If automated probes/drones, whatever you'd prefer to call them, are visiting us, then we would need to examine any evidence we have for such an occurrence in order to discover them.
As for the work of SETI - how likely is it that a civilisation thousands or millions of years ahead of us would use radio communications anyway?
Even at our early stage of technological developement we have discovered far superior ways of communicating information. Just recently, as reported by 'New Scientist' we have discovered how to create 'twisted light', which is found nowhere in nature and can be used to transmit vast amounts of data via laser, many times that of 'normal' wavey light! Who knows what other methods still await discovery, maybe hundreds or even thousands of years form now?
Lets face it, if we listened for the sound of Jungle Drums from deep space to find out if we've got company, we wouldn't have much chance of success.
