Firstly Some events in Bible donot disprove God
but it points to corruption of Bible.Refer Koran.
"How do ye say, We are wise, and the law (the Torah) of the Lord is with us? Lo, certainly in VAIN made he it; the PEN OF THE SCRIBE IS IN VAIN." Jeremiah8:8(KJV Bible)
The Revised Standard Version makes it even clearer: "How can you say, 'We are wise, and the law of the LORD is with us'? But, behold, the false pen of the scribes has made it into a lie. (From the RSV Bible, Jeremiah 8:8)"
