I do not imagine it being impossible for life to form within and around a black hole. In my mind I just see the black hole as a larger scale version of earth or any other celestial body that creates gravity. The earth could be seen as a volatile and violent place to an alien life form just as we view Jupiter or Saturn as inhospitable. Perhaps we just cannot imagine what a life form that exists on the sun may look or function like.
The main reason for my assertion is that we as human beings, accept the we are conscious and conscientious due to what we have discovered through neurology and biology. The main reason for our consciousness and self-awareness is located somewhere in our brain, right? Every thought you have or idea you conjure has a physical representation in the universe because you ARE the universe. You are as much a part of the universe as the sun, atoms, galaxies, quantum particles, and dark matter. You are the universe becoming aware of itself.
So when I say that life could possibly form and flourish in a black hole, I am coming from the angle that those types of life forms may be undetectable to us in ways that would show us that they are indeed alive. The matter that constitutes your brain makeup and consciousness, is everywhere in the universe and may be able to evolve, adapt, and come together in unimaginable ways on the edges of black holes.
At some points in the black hole, I imagine there being areas that are relatively calmer than other regions. It is in these regions where hyper-dense life forms could possibly emerge. It may not be anything like life we see here, but maybe it's a huge amalgamation of stardust and particle "sludge" within the black hole that has grey/white matter particles in it. These particles could in theory, become aware of the violent storm they live in and collect resources from the surrounding environment like early life forms did during early earth.
If we consider the stuff I just said, then perhaps the gods and deities of yesteryear are just black holes that collect information about the universe. Think about it. Nothing can escape a black hole, theoretically, so that means they are massive dumps of information that could potentially be back-traced using the laws of the physical world. Black holes have been around for a long part of the universe's history and have been amassing data the whole time. It isn't impossible for some sort of entity to learn things about the universe with all that data over a long period of time.
