I agree with much of that, but hybridisation with a truly alien species still makes absolutely no sense: forget all the Star Trek Happy Families With Aliens stuff: as I've said before, you have more in common genetically with a mushroom than with an alien, and a Hell of a lot more in common with a fruit fly (similar genes in similar places doing similar things). That's what common ancestry does for you.The morphological aspect of aliens is interesting. The variety of descriptions may demonstrate the conditions under which these beings are subjected to on their home planet or in inter-stellar conditions.
A life-bearing planet with less mass or gravity might encourage the development of tall beings with lower requirements for neck support.
The lack of light on a red dwarf might encourage the development of large eyes in order to capture as many photons as possible.
A homeless race, travelling on a massive survival ark because their star became a red giant and swallowed their home planet might have developed bizarre adaptative characteristics.
Migrating to a planet like the earth might be a very long adaptation process possible only through hybrid or genetic modification of their own breed so that they are eventually able to support the level of radiation, gravity or other parameters of our planet. (thus the abductions ).
The movie 'War of the worlds' demonstrated the ultimate effect of not adapting your breed to an alien environment. An intelligent race would understand the need for adaptive measures you would think ? Abductions make sense... when you need a new home world (yikes)
Aliens have the same chance of being able to hybridise with us as Jeff Goldblum has of being able to implant a virus in an alien computer from his Macbook...
So I don't buy genetic splicing. I do agree however that they might find it useful to study human physiology with a view to reverse-engineering aspects of it in their own species.
Although if they were going to do that, much of what they'd need is freely available information. And you wouldn't have to repeatedly abduct people over and over again: a cow works the same way today that it worked yesterday, after all.
Wild speculation time: If the itty-bitty spindly bodies exist and are also not "telepresence" machines of some kind, they might be the result of adaptation to a prolonged existence in a low-gravity environment (let's say a sub-light interstellar spacecraft that's actually a hollowed-out asteroid or something like that). It would make sense to make modifications on arrival to suit local conditions, and as part of that you might try to understand why the locals are put together the way they are (most of that paragraph might also apply if they're, let's say Homo futurus)
If the triangles are not of terrestrial origin I'd be almost willing to bet they're adaptations to operating in a planetary atmosphere or something like that (they also blend in a bit better obviously).
IMO, here's a somewhat plausible scenario if they're aliens:
1) Arrived in the solar system about 60-70 years ago in a generation ship, parked out among the outer planets somewhere.
2) Were surprised to find that the locals had been busy since their probes had reported back that a habitable system had been found (breeding and developing their technology), and were also in the middle of a global war. Best not to interrupt them when they're busy. Might not be responsive to the "We Are Your Gods" schtick at this juncture.
3) Also discovered they themselves had made physical adaptations to the long flight which were not great for living on a planet again, and that their craft designs and training were also more suitable for open space (hence the crashes).
4) Consequently they withdrew to the outer system and/or oceans in order to study the situation, make adjustments and also carry out a marketing campaign on the locals, aimed at seeding their culture with the image of an all-powerful, all-wise alien race. The Resistance Is Useless meme. Also encourage the Space Brothers thing wherever possible. In other words I'm suggesting we may be dealing with interstellar con men: Bill Knells From The Stars if you will.
(An alternative scenario is that they just said "sod this" and left, and that everything since then has been the combination of unrelated oddities and the growth of mythology).
