Reasons To Believe In God
All humans have an innate knowledge of existence of God and there is an urge to confirm it thru an external evidence. As a result they have come up with many theories similar to the ones you have mentioned. Those theories have resulted in man made religions or isms or ideologies called non-semitic religions. Semitic religions are those where prophets introduced the true concept of God. So the God we believe in is not the one that a philosopher or a Sufi has inferred thru observation of universe or meditations. God we believe in is the one that prophets of God have introduced us to.
True, thats possible. Anyone with a reasonable mental capacity should be able to infer God by pondering on the universe and looking for signs. Thats what God asks us to do in Quran. However, we may reach different or incomplete concepts of God thru this process as the observation can lead us to believe in existence of a supreme power or creator but gives us no clues as to why he has send us on earth and what he wants from us. Those details come from prophets.
I think this might help you understand innate/inborn/human nature and it’s interaction. Discussion 30094
