According to Yuval Noah Harari the unique nature of human being is to create fiction which has seperated us from other genus “homo”. Due to this we have surpassed Neanderthal man (our closest ancestors)
Everything we do today is just the fiction that we created long ago.
For example, any corporations, or organization doesn’t really exist on earth, it is just the fiction we have created. It exist only in the law suit (or in papers), which is also created by human.
Everything is a fiction.
