There is widely differing philosophical evidence for the existence of GOD. If one does believe that he exists and that he created the world for a particular purpose, then the belief that he was revealed to human beings and gave them instructions on how to fulfill their role in the world makes the most sense. The tendency to seek and worship GOD is deeply ingrained in the human psyche, as evidenced by the fact that all ancient cultures from the dawn of mankind have had some type of evidenced religion and worship in their history.
If GOD created human beings and instilled in them the urge to seek him, it makes sense that he would not leave them groping in the dark for an understanding of his will, but instead, it would be revealed to them and guide them in how to properly live their daily lives according to his word. Against the background of a belief in GOD, belief in Mount Sinai becomes equally self-evident and plausible, for if GOD exists, he is likely to be revealed to human beings. And here at the same time, we have received credible historical evidence of his revelation, and therefore it is logical to accept it.
