Brief Eternity?

It has occured to me that perhaps the only life after death is the genetic legacy we leave behind. Who are we without our minds? Without synapses firing and information racing along pathways that took a lifetime to cleave into a brain?
What is a soul....that deep unconscious core?
All on this planet share fundamental symbolism-archetypes. This is logical considering human brains are essencially the same. Human heredity is genetically closer than chimpanzees in the same country....and we populate the entire planet. The difference is experience.
Perhaps we are born with our ancestors experiences? Is it their genetic dispositions from which we inherit madness, genius, a taste for adventure or solitude ? Some of us a prone to dispondancy, others delight. Our reactions to experience are mostly unconscious, inherant habitual paths we travel. It is rare to encounter an individual that reacts to life consciously. Mostly, we just react out of one motivation or another that we never connect to or begin to understand. At times these schemas seem to seem to run deeper than one lifetime. Perhaps past life memories are just the experiences of our ancestors. Experiences that were pivitol to their development , now run through our veins. Does that affect the way we experience the world?
What are without these fragile bodies woven by every moment from cradle to grave?
So many questions....always more than answers....
There is a genetic legacy woven into every cell in my body.
I carry a brief etenity inside my skin.
maybe....???
