Over the past 100 years of exodian exploration, countless alien lifeforms have been discovered ranging from exotic plantlife to bizarre animals. While the discovery of alien life is no longer as shocking as it was a century ago, the continued research of these creatures has raised a number of strange questions that have yet to be answered by a satisfying scientific model.
As of today, over 16 billion distinct species have been identified across all charted worlds. However, the only lifeforms that appear to have what we call "sentience" are the five exodian races that migrated from Blimnor. While many scientists from the Gor Adukk Ma and The Family are not satisfied with the conclusion that exodians are the only sentient creatures in the galaxy, so far there is no evidence of such creatures living or extinct has been discovered. Why could life develop on so many worlds aside from Blimnor and yet not evolve intelligence equivalent to our own?
Another baffling discovery is that some alien creatures have been found on multiple planets. While there is often distinct evolutionary difference, the similarities are enough to conclude that they must have a common origin. While exodian exploration has touched hundreds of planets, the exportation of local resources and biology only accounts for some of this biological convergence. Some people claim that this is evidence of ancient astronauts ferrying creatures between worlds, others prefer the idea that it raises questions about whether creatures share certain evolutionary similarities no matter what planet they evolve on.
Some creatures have been discovered to be capable of surviving exposure to complete vacuum and even voyages through Zipp Space. While these organisms are often very small and lack advanced biology, it raises another question. Is it possible for organisms to evolve to live exclusively in the cold vacuum? While it is easy enough to point out that getting into space is itself a violent and energy-intensive process that has required exodians hundreds of years of industry to accomplish, others point out that evolving in space would not require that. Furthermore, the abundance of solar energy and the lack of gravity would allow creatures to harvest solar power, ride solar winds, and grow larger than anything terrestrial. And the infinite void leaves quite a lot of places where spaceborn creatures could exist without ever being discovered.
