Here's a fact - you've been born into this world at least once. I think you won't argue with that. A set of underlying properties and laws of our universe somehow resulted in elemental particles being assembled in a certain way that ultimately have formed your consciousness, your "sense of self", and, for some reason, bound you to "you". And to no one else. But, for now, let's skip the idea of what makes you - "you". And here's a question - can you name at least one good reason why it can't happen again? We don't know what state your consciousness have been before you were born. Even if that state is "nothingness", it is still a state, in a sense that we can name and acknowledge this state. But, we know that you were born, at least one time, and after you die, and your consciousness cease to exist, you will return again to this state. Let's name this state "pre-born" or "post-death" and let's agree that they are equal, because in both cases your consciousness is equally non-existent. Now, let's operate with facts: Fact 1 - You have been in this state before birth Fact 2 - You've been born into this world Fact 3 - You will inevitably return to this state after death (I know this is open for discussion, but if you disagree with this fact, I will gladly listed to a logic behind your reasoning) Considering the above facts - can you assume that there is a high probability that it won't happen again? I can compare this with the "Are we alone in the universe?" question. Assuming the universe is infinite, if life happened at least once on a planet, there is a 100% chance it will happen somewhere again, and on top of that - it will happen infinite times! (Infinite monkey theorem) So, assuming the space-time is infinite, and "you" happened at least once, the probability tells us that "you" will happen again. Infinite amount of times. Although that doesn't tell us anything about who or what you will be, or even if you will be anything resembling human is up to a question. I'm talking purely about "sense of self", about the identity of "you". So, back to my original and very simple questions - why not?
