Answer: The human is that animal in which the desire to receive grew. A human is some kind of unnatural mutation from the animate level, and in truth, he is called Adam (man) only after he attains the Creator, and before that he still belongs to the animate level.
Man is a form of bestowal that we acquire by resembling the Creator. Before this we call ourselves “human beings,” as with an eye for the future, because there is a potential power in us that we can develop and transform to be the true spiritual people.
Look at the disorder and rioting that is happening in the modern world. Is it worthy to call them Adam (Man)? It’s more like animals that have gone crazy. According to their behavior it is possible to say that the human has not changed at all from ancient times and he is no better in any way than the primordial savage man, and even worse. Since then, the desire to receive grew and brought us even more damage. None of our development went in the right direction and Adam is what is called only that part of us that is similar to the Creator.
