What is life, why and how it arises. On this path of knowledge, we will find that life does not have to consist of hydrocarbon chains and the habitat does not have to have water and oxygen, temperatures from 0 to 70 degrees Celsius. We will find out that there are life in conditions super-extreme for our opinion. May be at the end of this path we will realize that everything is life.
Life is not something unique, inherent only to the Earth, it always exists. when there is a possibility of its existence. Perhaps we know but superficially life as it exists on Earth, but we do not know it inside gas giants, stars, or in interstellar space.
The comprehension of life will provide an opportunity to learn how to survive for us.
