It matters. Jesus was killed by crucifixion. Crucifixion was a Roman punishment. How would the Quranic Jesus who went around preaching one God warrant the Roman punishment of crucifixion?

Your Quran is refuted by the fact no reputable historian goes there to learn about Jesus Christ.

Your Quran is refuted by the fact no historian ever says Jesus was not crucified.

Since you bring up Jesus not being God. How do you explain Jesus being the word of Allah and a Spirit proceeding from him according to your Quran?
