Or, more likely, because we are familiar with the fact that we were each born, we will all one day die, that our consciousnesses are emergent properties of our living neurosystems, and that no evidence has ever been shown to suggest that dead consciousnesses somehow recur.
No. Just no. We've been through all this, and your mathematical ideas are untenable. Let me try to explain.
If, 52 years ago my parents had written down the registration number of a car that I would one day own, the odds against them happening on the correct plate would be infinitesimally small. Indeed, the format for UK registration numbers has changed several times in that time and they would not have known how they would change in the future.
The likelihood of my owning any particular registration number when looked at before the fact would be similar to your "7 billion over unimaginably large". However, that does not mean that registration plates are reincarnated, or are anything special.
Many things are unlikely before the fact, but once they happen the likelihood is 1.
None of which have any bearing on this discussion, unless it is your contention that just because some things are strange, any strange things are therefore real.
This has already been addressed in your first immortality thread, but even credible NDEs are not evidence for ~OFL. They are evidence for a known physical response to a lack of oxygen to the brain, and they are culture-dependent which tends to support them being hallucinatory experiences caused by lack of oxygen. If you claim they are evidence for ~OFL, please explain exactly how something that happens prior to death, reported only when the person does not die, which has a physical explanation and which varies by culture has anything to do with the persistence of consciousness after death.
Again this was addressed. No OOBE has ever been shown to see anything other than what the person is able to view from their actual position. All the evidence points to OOBEs being halluinations brought on by stress, fear or drugs. I've had one myself, and I can assure you it was an hallucination brought on by stress and pethidine.
I've never seen a credible claim, do you have any? Not anecdotal, one that has been properly investigated.
Pop-psychology hogwash, if I may be blunt.
