There really is lots of evidence which demonstrates a real God / an intelligent Creator and your denials do not change that reality.
And I know that you have been told before right here on this forum in your face and eyes so the defect is within your self.
Fortunately I am happy to declare such things again and again, as there is nothing more important or more interesting in this life to tell:
Such things as like the earth as a globe spinning at high speed in empty space being held by invisible forces - that is a far grander and more fantastic of a miracle than anything said in the Bible or in any religious scripture. Walking on water or raising the dead is nothing in comparison to that.
The proof of the "Big Bang" is a real scientific proof of a creation day, and thereby it is a real proof of the Bible
chapter 1.
Plus the known existence of Ghost and spirits are another proof of there being a God.
And proof of a living active God can be found in the Bible prophesies fulfilled, see
HERE.
Of course there is lots more evidence for anyone who is willing to see.
Like I said calling it as the "original sin" is misleading as that terminology is loaded down with false and confusing nonsense, but I called it as a human defect and for that the evidence and reality of it can be seen in every person including our self and it is widespread worldwide, so it does exist and one only needs to acknowledge this which is so extremely obvious.

Genesis 3
Some parts of the Bible are false and even some "fairy stories" while other parts are not, and we do need to separate the parts.
