The modern age has generated a huge number of different opinions, creating great wealth of ideas but also great confusion and uncertainty. It becomes more and more difficult to discover the truth in a sea of possibilities. For example, there is still a clear contrast between the claims of science, now supported by molecular biology and genetics, and those of theology, which currently accepts also theistic evolutionary theory in human development. The aim of this essay is to seek truth from man's origin, in an attempt to recognize the Spirit of Truth amid the chaos caused today by a continuous proliferation of groundless information. To do this it is necessary to understand the historical, philosophical and as much as possible also scientific context of the specific civilizations of the period being examined, in order to give the right value to certain events, especially if of a spiritual nature. On the other hand, it will be important not to insist yet on what some modern historians now call the history of short duration, that which has prevailed until now (made of battles, dates, wars and events that have had little importance in the long time, also putting above all their own nation always at the center of events). This is the history of successive civilizations, with its moments of splendor and decline: it is in the name of the authenticity of events therefore that, although Science and Faith have at their base different motivations and methods of investigation, both must contribute to the search for truth, hoping for a reconciliation that allows us to reconstruct better and better not only the true history of humanity, but also a meditated gospel and incarnate in the modern world.
