The Existence of God and the Great Existential Mysteries

Since immemorial times, the human beings observed the heavens, reflecting on the great existential mysteries (origin, purpose and destiny of humanity), the meaning of life and the final reality after death, and asking different questions: Is there a God? How was the universe created? What is the origin of life and the human being? Is there a struggle between the good and the evil? Why is there so much suffering in this world? What is the meaning of human life? What comes after death? Why is there time? What is the destiny of humanity?Obviously, the existence of the Almighty Judeo-Christian God constitutes the greatest existential mystery and also contributes significantly to glimpse the other existential enigmas.
In addition, there are two alternatives (non-existence and existence of the Creator). The first argues that the universe, the life and the human being were generated randomly, as a result of an accident, while the second is consistent with the facts and the greater probabilities that justify the Lord's intervention in the origin and evolution of the universe, the life and the human being.
