My initial impressions:
1. You should read a book on the subject. I find all too often, Bible believers have only read sources that they agree with. It's a natural tendency that humans have, to avoid finding out anything that may contradict their position, because they become invested in the position, and literally afraid of the humiliation of wrongness. It's clear that you have done little argumentation on the subject.
After you have been hardened on the topic, you will know that there are exceedingly few fronts that you can argue your position, and not be faced with an instant answer, that you can't really refute. This has been done to death for 2000 years - with little progress, until Darwin and Hubble showed up. You are behaving the same way as a Muslim, Mormon, Scientologist, Zoroastrian, Wiccan, Hindu, Jew, .... They are all dead sure that their flavour God created the universe and is responsible for consciousness and order, but have nothing to back it up, besides Israel becoming a state. Seriously, WOW.
2. The book of Job, if you read it carefully, says that "He stretcheth out the north over the empty place.", which is insane. Job 26:7 says that God hangs the Earth upon nothing, which is a reflection of the old belief that Atlas or Turtles had to hold the Earth up against gravity. Yahweh, is just a bit more mighty, and can use his mind to do it. It's a flaw in understanding orbits. All in all, I'm surprised how few times the Bible sticks its neck out to reveal anything physical. The book of Enoch, written around 300BC, says that the winds, the sun and moon, all come out of "chambers", and that the Earth has mountains of gemstones on its corners. Even if there was truly any information about Earth in the Bible, nobody was able to understand it. The Bible clearly states that the sun is created on Day 4, so live with it.
3. Your idea that healing amputations would be too much of a miracle, does not work, because we only know what is usual by what happens. If amputees healed all the time, we would think nothing of it. Christians are torn between the idea that we have to live by faith, and on the other side, that we have been given proof, by the resurrection. WHICH IS IT?
I take the position that God has proven to us that the NT is full of lies, by putting a resurrection in it. Dead men do not rise, pigs do not become possessed, so therefore the NT is an obvious lie. If God wanted to make the NT believable, he, like Mohammad would have put no miracles in it. Then we would have to live by faith that Jesus was the Messiah, even though he did no miracles. The arguments really go nowhere.
4. You also state that Jesus was sent to clarify the OT. But when Jesus died, another guy called Paul had to come to clarify what Jesus said.... and then another guy called Mohammed came, and then Joseph Smith came. It appears that any dickhead can revise what Jesus or someone else said, as long as some Church endorses it, and people like you are prepared to go along with it.
Matt 5:19 states that Paul will go to hell. That's a serious flaw in the NT.
