Well then, we need to back up a bit. What is a miracle?
It's often defined as something contrary to natural law, but no-doubt we could extend it to such phenomena that are (at least presently) unexplainable to us, like, say, ESP.
If you accept one scriptural account as proof of God, it follows that you would have to accept all other equivalent scriptural accounts, which puts you in the position of believing in contrary things.
Again, this is another subject. I'm not saying that you believe it on the basis of that scripture's mere assertion, but rather, on the basis of some evidence within the scripture, e.g., scientific miracles. And of course, not all scriptures need be inspired or contain information that only supernatural intelligences could know.
The fantastical claims contained in the different traditions and scriptures of each of the worlds religions are no more or less authoritative or compelling than each other.
Maybe, but if there were one that contained miracles, it would certainly be more credible than the others.
