Possibility/Probability is the Measure of Existence.
All neurologically evolved organisms, including humans, first analyze the possibilities of existence, in order to calculate data and navigate through the physical world, hence the need for physics. Cognition is the computation of physical data, an innate function of the brain organ. Cognition, also known as “awareness”, directly develops into consciousness. What are humans aware of, if not reality? What is reality? Reality is the result of computation of cognition. For example, a human infant perceives through all of her senses. She sees, hears, touches, tastes, but understands nothing. Is she aware? Is she conscious? She is beginning to be and become. Her organic structures, developed by genes and instinct, lead her development toward consciousness.
As mentioned before, in other threads and forums, under different usernames, consciousness is the conclusion, the end result, the objective, the ideal, of evolution.
Humans measure existence as possibilities and their derivative probabilities. A probability is the derivative of a possibility. Possibilities are dictated by binary logic. Something exists, or it does not. It is possible, or impossible. Yes, or no. Possibility is 100% Probable. Impossibility is 0% Probable. Above 50% chance of existence, is probability. Below 50% chance of existence, is improbability. Every individual organism, including humans, has an innate calculator regarding chance, reality, and existence. A brain computes sense-data. Emotions represent systems of threat-perception and hope. Pleasure or pain. Food which nourishes you, or poisons and kills you.
Take a chance at life. What is your probability of survival? 95% chance of survival today? 1% chance of survival after 1 year duration?
Can life, reality, consciousness, and existence all become measured by science? Yes, they all can, by understanding the nature of possibilities and probabilities.
What exists? Does god exist? What does not exist? What is impossible?
Define your possibilities and impossibilities, humans.
What can you compute? How evolved are you?
