Leaving aside the theological question about whether the absence of a doctrine of life after death makes God “meaningless”, I think you’re wrong about science “taking away” life after death.
Like the concept of a supernatural Deity, the concept of supernatural immortality or post-death existence is not contradicted or disproved by science.
It’s simply that there exists no scientific evidence for either of those concepts. And you wouldn’t expect there to be, because science is, as others here have pointed out, a tool for producing materialist explanations of natural phenomena.
The NDE research that you seem to be so upset about is simply indicating that life after death is not a natural phenomenon. That is, there is no scientific evidence for it, any more than there is scientific evidence for God, souls, or miracles. That doesn’t mean that it doesn’t exist or that science can deny it or disprove it, as a supernatural phenomenon, in any way. It simply means that it is not a scientifically valid hypothesis.
Sorry, but that’s not good enough for scientific evidence. After all, “millions of people” have also experienced seeing ghosts or elves or extraterrestrial aliens or other things which are not accepted scientifically.
That doesn’t mean that ghosts or elves don’t exist in some supernatural way. It just means that no scientifically adequate evidence of them has ever been produced.
I always think it’s rather sad when religious people resent science, or call it “anti-religious”, because its theories don’t support their cherished doctrines. Aren’t you supposed to believe your doctrines on faith, because you have a personal, divinely manifested, conviction of their truth? Why would you even expect that a purely naturalistic/materialistic epistemological tool like science would or should confirm supernatural beliefs in any way?
Why can’t you just say “Well, I know that life after death is a fact, but science isn’t capable of detecting it because it doesn’t fall into the category of ordinary material phenomena.” A statement that’s honestly faith-based, sincere, and absolutely incapable of being disproved scientifically. What could be better?
Seems to me that any religious faith that demands confirmation of its doctrines from materialistic, non-theistic scientific theories must be pretty insecure and feeble. Why indulge in all these conspiracy theories about how “skeptics” and “atheists” must be somehow perverting science because they aren’t giving you the “scientific proof” you yearn for? Why not just respect science for the useful but limited tool that it is, and believe what you believe irrespective of whether science confirms it?
