There could be cavities with the right mixture of gas, water synthesized deep underground, and sufficient heat from plumes or just being at the optimum depth, life extracting the right minerals from certain rock types.
Could it be possible that original life might have originated from such places? Scientists do say we came from hot vents, but could we have come from deeper and migrated upwards? Is there other life deep in the crust that have been evolving longer than life on the surface?

I've come to the conclusion that Evolution does exist. It seems that every living being on this earth starts evolving and improving. There are several species that adapted to the enviroment in order to perpetuate, of course that evolution takes time and we can't live to see it happening . The only problem is that with our actual intelligence and power of understanding we can't seem to figure out how exactly our galaxy, our home, our planet came to this stage. All we have are theories. Because evolving takes so much time I'm afraid that the end of our race is inevitable since we won't be able to prevent the catastrophyes that will destroy us. And it's also hard to believe that we are alone in the universe who knows what other species evolved,maybe even faster than us. I must also confes that this whole God thing is the most unreliable source that could of lead to our creation, the only proof is a legend that lies within a book wich might have it's truth but it's also far from reallity.
