How many times does it have to be said that the absence of evidence is not evidence of absence?
Sometimes it is. When evidence would rationally be expected, and it's not there, then it is evidence of absence. For example, if someone says there is a dog in the kitchen, and you go into the kitchen and you don't see a dog. The lack of evidence is evidence of the dogs absence.
However, that is irrelevant to the question, because the absence of evidence in X is a reason not to believe in X. X may well exist, but it ought not be believed in until such time as there critically robust, scientifically valid evidence.
You've acknowledged that before, because you have said that as soon as an atheist claims that God doesn't exist, he must prove it by critically robust, scientifically valid evidence. You've said that before, so I'm not sure why you absolve the pro-God camp of that burden.
Seth wrote:
This is particularly true when the evidence of existence is denied and ignored because it does not meet some arbitrary standard that is in fact an iteration of the fallacy of begging the question which I call the Atheist's Fallacy:
"God does not exist"
"How do you know?"
"Because there is a lack of critically robust scientific evidence of God's existence."
"Why is the evidence provided by theists of miracles and visions and personal communications with God not considered valid scientific evidence?"
Because they are not repeatable or verifiable, and they are subjective accounts and personal experiences. Of course, it depends on the particular piece of claimed evidence. We can't address them all at once. You'll need to specify which miracle or vision or personal communication you're talking about.

"Why are they unscientific?"

No no. Miracles are claimed to happen, but aren't verifiable or repeatable. They can't be tested or observed. They are mere second hand reports and suppositions. That's why they are not scientific evidence.
A vision and a personal communication are just thoughts within a person's head, and are as such reports of something going on wholly within the skull of the person reporting the event. That is not scientific evidence in any context, whether the vision is of God or of a scientific experiment.
Seth wrote:
"Why are the claims supernatural?"
"Because they lie outside of known scientific facts."
"How do you know this?"
"Because theists say that God is a supernatural being."
"Have you tested their claims scientifically to see if their claims of supernaturality are valid?"
The miracle claims can't be tested or falsified, that is why they aren't scientific evidence. The visions and personal communications can't be tested because they are things a person claims to experience personally without anyone else being able to verify them. How would one test such a thing?
If a scientist claimed that he witnessed a miracle, and therefore M Theory has been proven true, or he had a vision that showed M Theory to be true, that also would not be scientific evidence. There is no reason to give religious claims or God claims a different standard.
Seth wrote:
"No, of course not!"
"Why not?"
"Because they are supernatural and therefore science cannot test them."
"Are you sure? How do you know?"
Because you said they were miracles, which are by definition untestable because they presuppose a special diversion from the normal laws under which the universe operates. A miracle is a special event, not a repeatable event, by definition. If the miracle was of a miraculously successful experiment, but no matter how many times other people tried it, it didn't happen, then it would likewise not be evidence.
Visions and personal communications can't be tested for validity because they are by definition things people see or experience personally, in their own brains, which are specific to them. If the vision was of a scientific experiment, it would likewise not be testable, and would be discarded as not scientific evidence.

"Because theists say so."
"Are the claims of theists always correct?"
"No, of course not, their claims of a supernatural Sky Daddy are nonsense."
"Why?"
"Because nothing supernatural can exist. There is only nature."
"How do you know this?"
"Because the Scientific Method says so!"
This is all a straw man - it's just what you're making up. The reason the kind of evidence you proposed are not evidence of God-claims is because they wouldn't be evidence of any claim, for the reasons stated above.
The scientific method doe snot say that that "nothing supernatural can exist." The scientific method says, that we look at a phenomenon and make testable hypothesis for it, then we do tests or make observations and we see if the results are in accord with what the hypothesis predicts.
Seth wrote:
"Is the scientific method omnipotent or omniscient?"
"No, of course not, it's just a theory about the nature of the universe that says that all things are explainable by reference to natural actions and without supernatural causes."
"Is God unnatural or supernatural?"
"Yes."
"How do you know this?"
"Because theists say so."
Like everything else, you bait-and-switch. First you claim that this is about consideration of certain kinds of evidence. Now it's about the definition of supernatural and natural. Well, I've explained pretty plainly why the miracles and visions and personal communications would not be evidence of any scientific claim, so there is no reason to consider them evidence of a God claim. It doesn't matter if God is natural or supernatural. Miracles, visions and personal communications wouldn't be critically robust evidence of whether the dog was in the kitchen. If someone said, I saw a vision of a dog in the kitchen, we'd say "so?" And, then we'd go look in the kitchen. If there wasn't something dog-shaped in there, then we wouldn't believe the miraculous vision to be true.
Capice?
