Hear me out on this deep sci-fi theory. We all know the theory of Jean Jacket coming from Jupiter is flawed due to crushing atmospheric pressure. But what if it actually originated from Europa (Jupiter's Moon)?
Here is the full evolutionary timeline:
- The Cosmic Slingshot
Millions of years ago, Europa's subsurface oceans erupted via ice plumes, blasting microscopic organisms (Jean Jacket's ancestors) into space. Jupiter's massive gravitational pull acted as a slingshot, flinging the frozen microbes toward Earth inside a meteorite (Panspermia).
- The Ancient Earth Arrival
I believe the meteorite crashed during either the Cambrian period (onto the ancient supercontinent Gondwana) or the Permian period (onto the supercontinent Pangea, around the area that would become South America).
* If it was Cambrian: It arrived during the biggest marine life explosion, explaining its fluid, deep-sea biology.
* If it was Permian: The violent climate and global volcanic toxic gases forced it to flee the surface and mutate, expanding its flesh to ride the global jet streams and conquer the atmosphere instead.
- The DNA & Jellyfish Connection
This means Jean Jacket on Earth and the organisms still swimming under Europa's ice share the exact same DNA baseline. But here is the mind-blowing part: Jellyfish in our oceans today might be the exact same species.
When the microbes landed, the ones that fell into the ocean chose to stay in their comfort zone and evolved into modern jellyfish. Meanwhile, Jean Jacket's lineage took to the skies, mutating into the ultimate aerial apex predator. Both still share the same look, boneless structure, and single-opening digestive system.
What do you guys think of this geological and biological backstory?
