“Life is the name that humans gives to the biological shape of the universal natural system.”
Like our human body, this universal system is evolving since the Big Bang inside this agglomerate of galaxies by the process of life’s cycle. This process is who makes our body changing shapes, like embryo from fetus, adult from teenager, etc. At universal level, biological shape comes from astronomic shapes ( the building block of DNA is self-projection of the building block of galaxies) which are the mechanistic shape, which came from atoms systems as the electromagnetic shape, which came from the soup of particles as the quantum shape…
All biological properties ( like metabolism, reproduction, etc.) already were existing at the ancestors shapes, some being expressed, another not, like our shape as adult express the reproductive property that was in potential state as a kid. So,… what is life? There is no exactly time that you can say your body changed from teenager into adult, its a slow and transitional process, so, there is no exactly time when biological shape began.
“Life” is a wrong and dangerous word that has prejudiced humanity because it does not know these hidden properties at our ancestors non-biological systems, then our bias for our separation from the Cosmos. Not knowing that biological system is merely product of an evolutionary universal continuum we created another dangerous concept: “origins”. As result we are searching the “origins of life” as an event that must have a mystical cause, like supernatural beings or magical causality by chance. There is no origins of anything, everything is product of transformation, evolution, in this long chain of events that began at the Big Bang, and is behaving like an exactly reproductive genetic process. Now we are watching the birth of a new systemic shape, which we call “consciousness”. Is it the last shape? Who knows?
Ok, each world view will have its definition, for sure we don’t know the ultimate definition yet. I think it is important that more people try to connect the real known data in different ways, each final result will be a different general picture, which will contribute for evolution of our knowledge. My world view is result of calculating evolution in the reverse way: while the authors of abiogenesis and Darwinian evolution begins at the “origins of life” and calculates from the past to the present, I began with the biosphere of Amazon jungle calculating from the present towards the past. And I can’t stopped at “life’s origins” because the calculation obligated me looking to this galaxy, then, to atoms, till arriving at an event similar to the Big Bang. From here there is no way to go ahead. Only seeing that the properties of life goes ahead, beyond the Big Bang. How I could define a kind of living ghost?
