Are miracles evidence of the existence of God?

[GrandizerII]

Granted, if one arbitrarily defines a miracle as an act of God...then one might say the existence of a realTM miracle would prove God existed.  But if we just define a miracle as something that is not explainable by natural laws or science, then I don't think it would be evidence of the existence of God.

If you define it that way, and we somehow saw ourselves observing such an event (though epistemologically, how could we know?) then it at least would be evidence for the supernatural imo. The question, for me, is if such a thing has ever been observed by us.

For argument sake, let's assume something inexplicable actually happened.

See, this is where you unknowingly jumped to a different sort of argument. If by "inexplicable", you mean you can't think of a naturalistic explanation for the event under consideration, then that's a different question. But the answer would still be somewhat the same, yes, it would provisionally be a piece of evidence for the supernatural. But you still have to consider all relevant pieces of evidence and not just jump hastily to one conclusion because of one piece of evidence.

First, one would have to know that whatever happened was actually impossible to have been due to natural laws or causes.  It seems there is enough we don't know about the natural world that that is unlikely to ever be known.

Good point. I agree.

Second, even IF one COULD know for certain that whatever happened could not have been due to 'natural laws' and/or nature, that would still leave other plausible explanations..e.g. some 'outside of nature' or 'supernatural' force that either acts randomly/inexplicably or that could be somehow controlled by humans or other beings with minds,  Of course this  explanation would be evidence of some sort of supernatural and maybe even that (some) human minds can access.

Another good point that I agree with. Basically what I said.

From a personal standpoint, I'm not convinced any actual miracles (events that cannot be explained through nature) have ever occurred, although I have heard some pretty remarkable stories from people I believe were telling what they thought to be true.

Same. For me, I can be convinced but they'd first have to make a very convincing case with observable examples to support their position. Otherwise, I can just remind myself of what I've learned in psychology and think up psychological explanations for these accounts that do away with the necessity for the supernatural.
