this is another example of an irrational response to my points.
yes, perhaps, the brain is able to detect things after all currently scientifically accepted signs of life have ceased... but that wouldn't explain how it's almost always, in a way that's 'accurate or consistent with reality', the case that a dead person can determine what happened outside his body.
What's irrational is to argue that not having an explanation for a phenomenon = having an explanation for a phenomenon. That is a logical contradiction which is why it is a formal logical fallacy to assert, and asserting logical fallacies is the literal opposite of what it means to be rational.
Setting aside the accuracy of your statement that what the brain has been shown to experience during these occurrences are 'almost always consistent with reality', an impressive quality of the brain is not evidence for the supernatural.
the only possible rational response to this stuff, is to question the credibility of the science
You can question the credibility of any scientist, you cannot question the credibility of science because science is nothing more than a method of understanding reality based on the fundamental principals of logic. Unless you can explain how we're getting our fundamental principals of logic wrong, then arguing against science is in effect arguing against logic itself which would again be self contradictory.
the problem with that, is that the science looks credible. given you dont even make that argument, you resort to just ignoring it
I'm not ignoring it, I'm pointing out why even if we accept the premises of your argument your conclusion still does not follow. The problem is not that you're working with facts here that I've disregard, the problem is that you are failing at the most fundamental level to understand how we come to know anything in the first place.
There is a reason science does not address the supernatural; because there is no method of testing something in the physical universe that could confirm what lies beyond it. We can only access and interact with the physical, so the only knowledge we can gain from that limitation would necessarily pertain to the physical.
None of this means the supernatural doesn't exist or that NDE's are not tied to the afterlife, it just means we could never confirm it and therefore it is irrational to assert.
