So are we talking sky critters here?
What ever floats your boat , if it is Quetzalcoatl space dragon energy worms then we should explore a way to approach this stuff from a zoological or preternatural point of view and no I don't mean old school kill it and stick it in a cabinet with a Latin name.
Sorry for being a bore, just wanted to say;
Our subscription to mainstream or outmoded dominant belief structures may ultimately influence or determine the success in getting somewhere with this. Ultimately with all of this stuff and the common element to say most of the threads running at this point on this board (as analogical onion layers) is that concensus reality or our idea of shared space and time doesn't make sense and doesn't really exist. Our consciousness of which they're could be many is the big daddy and offers us certain privileges. It operates levels of pattern recognition systems and imposes meaning on things that are meaningless to an agreed point or within mooted constraints, from the out there honed in taken as fact narrow world of "Slick" Simms to the scatter gun knitted factual causal imposition games of the fun knowing smirk of J P Farrell. Time, space, mathematics, psychology, etc.. None of this stuff actually means anything and is itself determined or defined by how we choose to define
it to our context, but is itself possibly a distinct entity beyond our imposition, so is it any wonder when something comes along that doesn't fit into our created reality our filter set up or world view and seems to exist outside our system that tests the limits of our shaky perception that we are puzzled? We scramble to impose order on it or some useless definition and for the most part it works, mathematics in its wondrous practicable abstract reasoning works to a point (although modern strides in cryptography is finding it hard to deal with very big numbers which they hope will be solved with "quantum" computing).
This is why the ETH is so seductive as it is an easy catch all imaginative blank slate existing outside our known kingdom, like bandying the word "quantum"or using magic in the Harry Potter plot sense, as long as we can, if we attach a bunch of meaningful statements, its existence is sanctified in our belief. Is it a possibility? Yes but it's just a hypothesis at best and to say that it is rational or logical is is itself irrational and illogical and by its own rules, bends them to allow "fiction posing as the cusp of factual reality but not quite yet, but nearly there passableness", sitting well with people who can't fully take the "fuck it" leap of full on imagination but needs the touch stone foot on the ground of cold science in all its 1950s glory. I love that world, it's seductive, I'm surrounded by it at home with comics, dvds, novels, computer games, figures etc.. but with its ideas of flying men, mother ships, sentient droids, robot humans, time coils, laser whips, mind melds when applied to the real world anomalies of paranormal and UFO experiences it is just camp pedestrian nonsense and doesn't explain the big questions and that if you really thought about, doesn't make any sense in the whole scheme of things and particularly not if you base this on the myriad of abductions, contactee reports, UFO reports, humanoid sightings from around the world that if were to all be believed in would be just plain chain pulling tricksterism. But I'm not in
thrall to this science fiction as much as I want to be, and this is where our imagination can be used against us, take heed. I understand it's our convention it's part of our system and our rules and how our brain is mapped, the safety that is to try to stay within the meagrely tangible. The "reality" is we don't know enough about our own world or how our consciousness works to begin to definitely subscribe to a hypothesis wholeheartedly as to what some other thing is. Nor do we know what lurks behind the doors of the privileged hierarchy and puppet masters. Rather than taking this ridiculous authoritative stand point of imposing warp drive time travel, Wells, Arthur C Clarke and Heinlein as hard science fact why not think, actually it could be anything beyond my little brain and that I know the distinction between fact and fiction and maybe there is an excluded middle? Look at this;
Yeti crab. This didn't exist until 2005. Did it exist before that? Of course it did.
Look at these:
Mushroom spores. Heres an alternative tangible way at looking at possible alien communication a la "The Inner Light" (Season 5, episode 25) next generation.
as Valee said
"I will be disappointed if UFOs are nothing more than spaceships."
oh yeah...
"One theory which can no longer be taken very seriously is that UFOs are interstellar spaceships."-Arthur C. Clarke
