An experience through Monotheistic Religions

What was the first religion of man? There are alot of different answers. These depend on what man thinks is his own origin. The early chapters of the Bible showed that religion was not invented, did not evolve and was not discovered by man. From the day God created man, the latter knew the Creator-God who made him. Moreover, from the time of his fall, man worshiped God through sacrifice. The two characteristics of the original religion are Monotheism and the practice of animal sacrifice. These are shown and found in the Bible. Here we see that God was God and man could not approach Him in his own righteousness because of his sins.
