Argument from scriptural miracles
The argument from biblical miracles states (more or less) that because a holy book states that people witnessed miracles, people actually did witness miracles. This is often associated with a holy figure such as Jesus or Gautama Buddha and is interpreted as evidence of their divine character. It is a form of argument from miracle testimony.
- "The miracles of Jesus and of the Bible writers are God's stamp of approval on their teaching. This witness testifies that there is a God who possesses supernatural power. And since the Bible writers did miracles, they must have been guided by God's power. Likewise the fact that Jesus did miracles confirms the truthfulness of His claims that He was the Son of God."
- "Further : some parts of Scripture containing an account of miracles fully sufficient to prove the truth of Christianity, are quoted as genuine, from the age in which they are said to be written, down to the present : and no other parts of them, material in the present question, are omitted to be quoted in such manner as to afford any sort of proof of their not being genuine. "
Jesus is said to have performed many miracles, including walking on water, raising from the dead (both others and himself) and healing the sick by touch.
There are relatively few claims of Muhammad performing miracles.
- The main example is said to be the scriptural inerrancy of the Qur'an. The Qur'an is also said to contain scientific foreknowledge, prophesy and significant numerical properties.
- Some interpretations suggest Muhammad split the moon in two. (Surah 54:1-2 ) 
Gautama Buddha is recorded as performing many miracles.
Assuming the Bible is accurate
- Main Article: Argument from scripture
This argument assumes the Bible is true, which is questionable since it is full of false statements, contradictions and written long after the events by non-eye witnesses.
- If the Bible is assumed to be true, the Bible confirms that God exists (e.g. Genesis 1:1) and the argument is not required.
- If the Bible is not assumed to be true, the argument is based on an unsupported premise.
Accepting unreliable testimony from confirmation bias
- Main Article: Outsider test
There is no other evidence of the miracles apart from the holy book that a man walking on water, or feeding 5000 with five loaves and two fishes, or turning water into wine. We are left solely with testimonial attestation of these events.
Imagine taking a number of tribesmen from New Guinea and subjecting them to a magic show. Afterward, it would be possible to collect as many testimonies as desired to the "fact" that, for example, the magician was beheaded by a guillotine, but was re-integrated and completely unharmed several minutes later. These testimonies are contemporary (indeed, as contemporary as is possible) and mutually corroborative, Moreover, these witnesses could be questioned to any degree. What would be our reaction? Would we take these testimonies as evidence and conclude, based only on them, that the magician really did have his head cut off and survive? Or would our incredulity at the likelihood of the event override the testimonies and lead us consider other alternatives (the tribesmen were fooled, they aren't remembering correctly, they're lying, etc.).
Would adding centuries of possible embellishment and distortion make the testimonies more, or less, credible?
The reason we reject their testimony is that we have prior experience that these things do not usually occur. We base our beliefs depending on the weight of the evidence, considering that such things might occur outside our experience and the possibility that the "miracle" witnesses were mistaken. This standard of evidence for miracles was suggested by John Locke and in David Hume's essay Of Miracles.
The primary reason such miracle testimony is accepted is that the believers' incredulity are overridden by their a priori assumption that their god, or Jesus, is all-powerful; the testimonies are worthless without it. This will shift the discussion in that direction.
