I appreciate the open-minded approach you have to this subject and I enjoyed reading about your theory, but actually do wish that you would have gone
into detail about possible extraterrestrial/extradimensional entity-characteristics and behavior because such speculations are good food for
thought.
Now, knowing that we only have our own reality as reference when speculating about this subject, we are limited to our physical senses to explain the
nature of the phenomenon; despite knowing, although often forgetting, that our senses and level of intelligence specifically limit the scope of both
our imagination and perception of reality.
For example, the majority of the general public and conventional scientific community subscribe to the abiogenesis and evolution theories, so we use
these as points of reference often ignoring the fact that there have been numerous scientists who oppose both theories, especially the abiogenesis
theory.
If abiogenesis is the only process through which life comes into existence on a planet though, then we may find life in the Universe to be rare as
extremely specific conditions are required for this particular process to take place.
However, if this is the case then the possibility that planetary bodies are contaminated, if you will, by DNA and RNA molecules as well as microbial
life-forms from meteor and comet strikes may even the odds a little and could potentially explain the diversity of species that have existed and are
present on planet Earth itself.
If the panspermia theory is accurate, then we very well could discover that life is either common or abundant in the Universe, and if the evolution
theory as presented by Charles Darwin is correct, then we may also find that extraterrestrial life-forms resemble terrestrial ones based on the common
DNA ancestry, that may have originated billions of years ago somehow, somewhere in the vastness of the Universe and has spread throughout the cosmos
through several and various means.
So we could even find bipedal and perhaps even hominoid extraterrestrial species on other planets if evolution ultimately is striving for a common
structure of anatomy, physiology and biology resulting in features that resemble those of various species on Earth, if intelligence is a universal
phenomenon that cooperates with evolution and thus produce life-forms like ours in environments that are similar to Earth's.
This however makes things even more profound, because it would mean that almost every type of animal order could potentially reach a stage of
bipedalism (probably only land based ones though) resulting in biological diversities of sentient species such as reptoids, amphibioids, arthropoids,
hominoids and so on.
Potentially even fish, dolphin, crab- and octopus people.
...and spider-people!!!
Personally, I think the odds are rather high that the Universe is litterally teaming with life and some of the species are probably so far ahead of us
that their technology would seem like magic and intelligence would be interpreted by us as insanity instead.
I love speculating about this subject! Good thread!
*EDIT*
And, as always, I begin to speculate about the subject and begin to compile a reply and completely fail to even mention as to who they are, why they
are here and so forth which was my inital intention of course. My apologies!
