If ET exists....why don't we hear from him????

I think that this is probably the most cited proof that no extraterrestial intelligence exists. Myself I think that if they exist (and I'm pretty sure they do, like is said if they're not out there it seems an awfully big waste of space!) they would not really interfere with our development, a little like the 'prime directive' in star trek. They would however be interested in our development. So how could they observe us. Well we have the paranoia of 'the invasion of the body snatchers' and then we have 'symbiotic' life forms which are not parasitic, but at least neutral, maybe Commensalistic, and hopefully mutally beneficient as in the show 'Stargate'. Myself I like to ponder Shakespeare and his play 'As you like it' wherein he states 'All the world's a stage, and all the men and women merely players.' Here is my reasoning that they be absent from our view, but very much 'here'. If a world exists outside our star system, maybe they watch us as we watch ants, from beyond their perceptions. The ants may sense we are out there, but not be able to see us. Thus maybe we are being watched, just from beyond our perception, probably watched in a cross between a drama and nature programme. I hear you ask how? Where are the cameras?? Well I propose that they are there all around us, just as Shakespeare posits 'all the world's a stage'. To develop the idea one must know a little about frame rates, and how the eye can be deceived. If technology existed to manipulate linear time, it would be possible to insert observation equipment as it were in the gaps/behind time, present then absent, quicker than the eye could perceive, then ET would sit back and watch a presentation similar to a cross between Richard and David Attenborough.

Like the axiom goes 'Quis Custodiet Ipsos Custodes!'
