So you submit, that in spite of the overwhelmingly long odds against, it... you (being somehow special) having been raised and indoctrinated in the traditions of the Islamic faith, would have rejected that faith in favor of Christianity.
Sorry, but I don't think you're being honest with yourself.
Christianity believes that Jesus Christ is the God of Abraham. Islam doesn't. This is the fundamental difference.
If Islam claims to worship the God of Abraham, and Isaac... why did they keep the crescent moon as their "logo"?
