If reincarnation is what happens, then reincarnation is what happens.
That doesn't seem to be very logical, though. The population of the planet at the beginning of the 20th Century was about 1.65 Billion people and by the end of that Century it was about 6.65 Billion.
If the planet relies on reincarnation to re-populate, where did the additional 5 billion people come from?
Keeping religion out of it (but it's pointless to try to pretend that religion doesn't exist) then [and I'll limit the consideration to monotheism - I have a simple mind and I don't want to get bogged down in sums
] there are 2 possibilities:
1. There is a God (and some sort of afterlife)
2. There is not a God and when you're dead, you're dead.
In the first case, you die and there's God. If you believed in God, you might get all smug about it (though God might just have a way of wiping the silly grin off your face ) and you get on with your after-life. God is with you for all eternity.
If you didn't believe in God, you might be in for one hell (or heaven
) of a surprise.
Then there's the second possibility. There is not a God and when you are dead, you are dead.
You were one of those who believed in God, so - just as you thought - God is there for you for all eternity. Nobody actually knew this, but 'all eternity' suddenly became a highly-subjective (and very finite) period. You reached eternity at the instant at which you died.
(If you didn't believe in God, you were right - If you want to Pass Go; if you want to collect your £200 - feel free! You can crow about it, if you like - Nobody's going to hear you, because you are dead and there is no God.)
I have indeed had surgery - the most recent event was a week ago. I was awake and then I was not awake. My heart was beating and then it was not beating. Then it was disconnected and they were doing something to bits of me which included refrigeration (probably unpleasant, but I didn't feel a thing) while I was getting an engine rebuild.
Then I was awake again. I've no memory of anything from the time I became unconscious to the time I regained consciousness. Why should I have?
Then again, I go to sleep every night and (although I do dream - just like everybody else) I often wake up with no memory of the interval during which I was asleep.
Why should I have?
Shortly before the operation (And it was a very short-notice op) the surgeon asked me whether I needed time to discuss it with my wife. "Of course not! Do it."
Then he went through all the garbage about 'Every operation involves a degree of risk ...' (I suppose they have to do that, really.) I stopped him. "Yes, there is a risk. A small risk. There is a much larger risk if you don't do the operation!"
He said: "Aren't you worried?"
Simple answer: "No."
I will die sometime (I hope!)
I don't care about being dead - that's going to happen.
The 'dying bit' itself could be a problem. Some ways are certainly easier than others.
