Finally, we can define life, not organically but from a spiritual point of view, as was simulated by some philosophical trains of thoughts or doctrines.
Proponents of the anthropic principle, for example, consider that life primarily represents our consciousness, whether it be the image of a superior being (strong anthropic principle) or the laws of nature that guide the evolution towards increasing complexity (weak anthropic principle).
At this stage of the study, we discover that life can not be defined using the same principles. It is likely that our search for a precise definition is utopian, each stage of evolution defining its own rules, life actually appearing gradually in increasingly sophisticated systems. Gravel is inert, crystals grow and are defined by their purity, clay has memorizing and chaining capabilities, proteins ensure the cells work, viruses have reproductive capacities, protozoa are autonomous, and metazoans are organized.
We believe that life concerns only the highest evolved bodies in this evolution. But by wanting to label to each link in the continuous chain, by seeking an exact definition of life, by considering only its extremes or by arbitrarily stopping its properties, we will find ourselves in one stage or another in the face of confusion and hampered in the paradoxes of its language. A good definition of life must approach this concept from a more general point of view, observing the properties and behavior of matter and how it gradually climbed the various levels of complexity.
The purpose of the file on bioastronomy is to try and understand how the first cell appeared and whether it appeared on Earth or elsewhere in the universe.
We will also need it to define a cell and its properties, its advantages and weaknesses. Molecular biology and biochemistry will lead us to the bricks of the genetic code.
Once we have elements of solutions, we will try to find out what advantages they have earned to live in community. Miller’s experiment, the principles of thermodynamics, and Darwin’s theory will be the keypoints of our discussions.
Our point of interest will finally focus on the efficiency of the functions of this organism by observing how life has adapted in extreme environments. If we can understand these mechanisms, we may be able to unravel the mystery of life and offer some ideas about its extraterrestrial evolution.
