An Ultimate Mystery Behind Human Existence

This book will address the dilemma of existence and human existence in particular. Questions about the nature and meaning of existence have preoccupied humanity for thousands of years, at least since the psychological revolution 50,000 years ago, and since then many great thinkers in human history have grappled with the subject. Of course, there must have been individuals before the philosophers that we know of who dealt with the meaning of human existence, but unfortunately none of this has come down to us. I suspect this because everyone can use their intellect, as already demanded (""Have the courage to have your own intellect / reason!""). And while not everyone looks for the first and last reason, they have most likely wondered why.
