Begin with a study of Quantum Physics and Einstein’s General Relativity. Both disciplines provide the very laws that govern the existence of the universe. There are myriad books available, so no list is necessary. Progression beyond both subjects (by delving into String Theory and so forth) are option.
Continue with a study of Big Bang Theory, which essentially describes the origin of the universe from Planck’s Period to the present. The background knowledge of Quantum Physics and General Relativity will definitely augment the reading.
Then, read the book, “Who We Are and How We Got Here,” by David Reich. The latter appears to be most current book covering the research into the human genome and its application in discovering the origin of modern humans and the human migration pattern since that time. There is little doubt that an understanding of the animal origin and evolutionary process that produced “modern” humans will be alienating and disconcerting. All fictional stories of human origin and exceptionalism will be discarded. All that’s left I’d the human animal, one that continues to live in denial up to this day.
Finally, read the book, “The Denial of Death,” by the Great Prophet, Ernest Becker. The truth will become entirely self-evident such that there will be no need to delineate upon the matter again in these Notes. The truth will become the TRUTH.
