Without a Creator, nothing can exist. Every single soul knows that he is existing and that his existence is dependent upon a Creator he knows for sure that he cannot create him self. Therefore it is his duty to know his Master, the Creator. Man is a unique creature. God established man to govern over all other creatures in this world.
Man is born pure and sinless and is given the choice to do righteous deeds or indulge in sins.
The Creator, out of His abundant Love and Mercy for mankind has not left us in darkness to discover the right path by trial and error alone. This message is conveyed towards successive generations of man through the different prophets, all inviting mankind to the same path. However all the earlier messages or revelations from God were distorted by people of later generations. As a result, pure Revelation from our Creator was adulterated and polluted with myths, superstitions, idol worship and irrational philosophical ideologies. The religion of God in a sense was lost in a plethora of religions.
