I agree with you. Now all you/theists have to do is to demonstrate that these seemingly miraculous events actually happened, so we can then go about the business of incorporating such events into the known laws of nature.
Which for a theist is obviously a theistic one. The idea that a theist would see God as a law-breaker, let alone that miracles can only be called such if God has broken some sort of law, is silly and does not correspond with what most theists I have ever met, regardless of tradition, generally think. Rather, most would consider the "law of the universe" to be God's to enact as he or she chooses.
All the evidence we have today tells us that humans can't walk on water or fly up into the atmosphere without the aid of some technological device. Such a claim goes against everything we know about how the natural world works. And we have very little evidence to support the claim that such events occurred, as reported in the Bible. Therefore, the probability that these claims of a seemingly supernatural nature are true is extremely small.
If theists were somehow able to reproduce such events under controlled, repeatable conditions, and demonstrate that these events were being driven by the will of their god, that would be a different matter. But that is not the case. Pending such demonstrations, it would be unreasonable, or even foolish to believe the proposition that a god exists that can bend nature to its will. Wouldn't you agree?
