Stretching the truth
Now, now Alpha, you're stretching the truth. You did not say, "MOST LIKELY does not believe Jesus existed", you said, "I think it is safe to say he believes Jesus Christ did not exist." This seems to be typical of Christians, they change their story to try and win the argument.
Olopo did not say that the teachings of Buddha and the teachings of the Koran are the same as the teachings of the Bible, he said that there is much in the Bible that is true, and much in the teaching of Buddha and the Koran that is true. This does not mean they are the same.
"... if one can prove the Bible to be the word of God, then this CAN show Jesus Christ existed." That's a pretty big IF. I don't accept that the Bible is the word of God, therefore it does not show that Jesus existed. Noboby can prove the Bible to be the word of God, that's why the Christian religion requires FAITH.
