First, more than 5,000 Greek transcripts of parts of the New Testament existed before Muhammad was even born. Second, the Torah predates the birth of Muhammad by over 1,000 years. Finally, the Koran talks about some of the same people in the Torah and hints at the gospel.
To negspek me anonymously and then claim the Koran predates the Bible is absurd, or simply pure ignorance. The easiest thing to do without making yourself look stupid is to just negspek without comment. That way you can simply register that you disagree to the point of cowardly anonymous negspeking without also being historically wrong.
