From time to time, ideas like this seem to attract attention; I recall that a book along these lines even became a best seller some years ago.
But, no, the Bible doesn't support such an idea, nor is there any evidence for it in the Bible. Instead, the Bible clearly tells us that we aren't dependent on some supposed outside source for our knowledge about God -- because God has revealed Himself to us, directly and openly.
How did He do this? He did it first of all by implanting something of Himself within us -- what we call our soul or spirit. Although sin has obscured this, down inside we still know God is real, and that we owe Him our lives. God also has revealed Himself to us in the world around us; as the Bible says, "The heavens declare the glory of God; the skies proclaim the work of his hands" (Psalm 19:1).
But God has shown Himself to us most of all in Jesus Christ. Christ wasn't just a great teacher or profound religious leader; He was God in human flesh! Do you want to know what God is like? Look at Jesus Christ -- and when you do, you'll not only realize that God exists, but also that He loves us and sent His Son to die so we could be saved.
Don't be confused by the speculations and myths people dream up about God. Instead, by a simple prayer of faith ask Christ to come into your life -- and He will.
