Hi Zardoz, how'z it goin?:-)
Her body was chilled to 60 Fahrenheit, it was drained of blood to deflate the aneurysm for surgery, and her heart and lungs were stopped. The EEG recorded no activity in the cerebral cortex, and the point of those earplugs was that they contained earphone speakers whose clicks, if picked up by the ears, would produce distinct signals (evoked potentials) in the brainstem, as recorded by another instrument. Not only was there no sign of cortical activity, there was no sign of brainstem activity.
To quote Spock, "she's dead, Jim."
So. To paraphrase your points:
"The most interesting parts happened before they made her temporarily dead."
OK, so at least you're not quibbling over whether she was able to perceive, accurately and in detail, goings-on in the operating room around her despite being knocked out by general anaesthetics and having her eyes taped shut as well as her ears plugged tight. By the way the technical term for what she reported at the initial stage, is "an out of body experience with objective correlates" (to distinguish from the type of OBE whose content is more dreamlike and can't be verified).
If I'm not mistaken, that constitutes acceptance of, at least, remote viewing, and possibly OBEs as such. Sounds like progress to me.
"But she wasn't really dead because they brought her back and now she's alive."
She was quite dead by every current medical definition. Heart, breathing, and brain activity stopped. Blood drained. Body temperature down to 60 Fahrenheit. Deader than a doornail.
The definition of death you're using is, "does not come back," in other words, "not dead until composted." That is not the accepted definition in medical science. And in any case, it's pure obscurantism because it pushes the entire subject matter outside the realm of testable hypotheses, in other words, outside of science. That would be the "God in the Gaps" method, that's also used to justify conventional religion by pointing to "anything we can't presently explain" as evidence of God, and as the explanatory gaps narrow, the definition of God narrows along with.
"There might have been brain activity the EEG missed."
According to which, so long as there is any evidence of consciousness, it must be hiding out some place in the brain that is magically eluding our every attempt at measurement! Now as well as God in the Gaps, we have Consciousness in the Crannies, or perhaps Materialist Monism by Mis-measurement!
That would almost fly except for those little clicking ear speakers and the absence of an evoked potential signal in the brainstem. Nothing in the brainstem, nothing in the cortex, and the patient's blood drained from her brain which is chilled to 60 Fahrenheit along with the rest of her body. When you perform a procedure that shuts down the brainstem as well as the cortex, it's safe to say that the stuff in between is shut down as well. Unless you want to operationalize the variable by putting the brain in a blender just to be sure! And that also fulfills your "don't come back" criterion, but once again, that ain't science.
There's one more piece that Zardoz didn't comment on, from the Wikipedia article: "She may have had the claimed experiences before or after the standstill, when she was merely under general anaesthesia and the brain was still active."
In order for that to be true, we would have to have a completely anomalous finding of continuous memory through a state of deep general anaesthesia! Fact is, people do not have continuous memory through deep general anaesthesia. Memory recording basically stops as a person slips into unconsciousness: there is always a gap, just as when a person faints or gets knocked out in an accident. "The last thing I remember, the light turned green in my direction..." Same case with going to sleep: consider all those times you've gone to bed thinking "I have a good idea but I'm not going to bother writing it down, I'll think of it in the morning," and then the next morning, "Oh darn, what the heck was it I thought of last night?"
By this time the monistic explanatory entities are multiplying faster than ghosts at a new-age seance! So many entities that Occam himself (or Ockham if you prefer) would be slashing about with his razor to slice out the superfluous ones and get down to the meat of the matter.
Far more elegant to forego Consciousness in the Crannies, and go with Chalmers' intereactionist hypothesis.

And if that's not enough, the Wikipedia article is obviously biased, as revealed by the use of quote marks around the word "death" in "near death experience," e.g. near "death" experience. That use of quote marks reveals the bias that the word "death" should not be used in the term "near-death experience," because (according to the biased view) death is only death after the body has been fed to the worms. Once again, this is at odds with the consensus of medical science that death is defined as the absence of brain activity.
It also reveals a complete lack of familiarity with the subject matter. The term "near-death experience" was chosen by Kubler-Ross, Moody, Ring, et. al., precisely to specify that these experiences occurred "near" death but that it was not known at the time whether they occurred "during" death as per the definition of the absence of brain activity!
In fact, at the time those individuals were writing (mid 1970s), the standard medical definition of death, enshrined in law in most states, was cardiopulmonary death: cessation of heart activity and breathing!
So, according to the definition of death in those days, Kubler-Ross, Moody, and Ring, could very easily have claimed that those individuals were dead, dead, dead: they had their characteristic experiences after their hearts & breathing had stopped. Instead they did the right & proper thing and claimed merely that their patients were "near" death. They were "near" death, they were not near "death." Subtle but important distinction.
Advances in resuscitation techniques kept pushing back the frontier, with the results we see today. It is highly probable that as resuscitation techniques continue to improve, and as "standstill" procedures become more common (here come the ageing Boomers, unwilling to forego their eternal youth, no doubt plenty of guinea-pigs for such experiments), we'll see longer and longer periods of brain death before resuscitation, and more and more of these cases, and increasing degrees of overlap with reported experiences and verifiable observations.
As a result we will also see an erosion of the claim of exclusive legitimacy made by various religions in their more extreme manifestations. Those of us who are familiar with the NDE research can already see this coming, via the reports of pediatric NDEs: whereas adults usually have religious imagery that corresponds to the denomination in which they were raised, children have cross-denominational imagery, most often Christian children meeting with Buddhist and Muslim entities.

Yo, Yap:-)
Of course it doesn't prove the existence of God! Failure to disprove is not proof of the converse.
In fact, the existence of God as defined in Western monotheism or the Abrahamic traditions (Judaic, Christian, and Islamic) is one of the very small number of points that is entirely outside the realm of empirical science.
The reason being, an omniscient God would be aware of all characteristics of an experiment, and an omnipotent God would have the ability to alter the outcome of the experiment to suit Its intentions.
Think of those editorial cartoons showing lab mice talking to each other about trying to outsmart the scientist:-)

Jason scores again!
Strictly speaking, agnosticism is the only scientifically supportable position with respect to the existence of God, because strictly speaking, as per above, the experiment can't be done. Thus, religion, as with aesthetic beauty, remains in the eye, or mind and heart, of the beholder, or the believer. And thus the separation of church and state remains an essential for a truly free society.

However we can do the experiment re. consciousness and the brain. And the further modern medicine can extend the limits of shutting down the brain temporarily, the greater the opportunities for observing what happens to consciousness during that period.
