Three of those five points contained scriptures (the other two are human conjecture). None of those three would a person of average intelligence and without preconception take to mean that Jesus is God, much less the trinity.
The father is clearly and undeniably said to be God many times. I wonder why the bible isn't anywhere near as clear about the son being God? I mean, God could have made it just as clear very easily. Perhaps because that's not what the Bible's trying to communicate, because it isn't true. That seems to be the most obvious reason.
