Irl scientific edition of OP:
In some corners of science there is the possibility of
there being multiple individuals in the world. A (seemingly) infinite number of individuals
where anything manifested from the established probability by entropy etc is possible.
Considering this seeming infinity, there could be an
Imaginably infinite number of variables for the factors that make me myself a future common ancestor and a convergently evolved derivate of other common ancestors that will in turn lead to many possible parallel derivates.
Physical so also mental since their brains are physical. Perhaps somewhere along
the lines of those infinite variations one derivate/convergent is
the random nonhuman species (that won't exist perfectly as it does right now in a billion years) I came to assimilate as cool through my sensing processes over time
So we all can imagine that convergently the actually physically possible ideas of beings that we like exist
which gave us the initial idea and the idea for our characters we post to give further ideas for new furries to base their characters on on this forum which will in turn influence others to think imaginatively.
A group of environmentally derived thus attuned beings known as animals that evolved from
those incredible single cell organisms (we shun from but can't genuinely recreate because the process that makes them exist exists like its own force out of reactive chemical patterns) which evolved into everything that inspires us to imagine all we can imagine somewhere a few billion years ago.
An interesting observation at least.
