Dude, he/she/it is not coming back. The whole "number of years" thing is pointless. Moses was said to live to the ripe old age of 950 or something. LOL.
The reason Jesus will not return in any timeframe is because there is no "afterlife". Therefore, Jesus was not "reborn". And neither is anyone else.
You can do this thought experiment yourself. Where were you BEFORE you were born? Where is your memory of it?
Cannot recall it? Interesting. That it is because it does not exist. The same way you will not exist after you die. Same shit with Jesus.
You're dancing around the question...
The "I" in this refers to the "you" of you. Your ego/personality. Your essence. Your identity as an individual. It comes from your brain, and not from some outside realm where "you" might exist. If you cannot remember yourself from one life to the next, then there is only one "you".
Jesus himself said "I die daily". What he meant was that he falls asleep. The only reason you know you are alive is if the body wakes up the next day, and your brain continues to propagate your personality. Once it goes away, i.e. dies and does not wake up, "you" are done forever.

I tried to think of a clever way to answer you. I thought about responding to this: "Where were you
BEFORE you were born?" with this: The "I" or "You" part of a person must be passed on from another person, because only life can bring forth more life. This seems to be true with plant life as well. A dead seed may have all the needed coding to produce a new plant, but if there is no life in the seed, then it will not germinate.
So, your life came from the life of your parents. As I already mentioned. However, you were not in your parents' conscious thoughts...(as far as I know

) and we have no memory of this existence before our own consciousness began.
To further explain this I was thinking about using the example of the elements sodium and chlorine that combine to form salt (sodium chloride). Before they were a salt compound, the sodium existed separately from the chlorine. Put together as salt, they have new characteristics. But then, after having got that far, I wasn't sure where to go with this for death.
Then I thought about trying to use Einstein's theory that "Energy cannot be created or destroyed." New life isn't a new creation, it is life being passed on from the previous generation, so this fits nicely. And so perhaps life cannot be destroyed either, just as energy cannot. That seemed like a good point until I remembered that plant life and animal life most certainly does get destroyed....they do not go to heaven and once dead, they are dead.
Then I thought about the many stories of people that have died and seen white lights and experienced things, and I think some of that may have truly happened, but then often those stories don't match the Biblical description, so I discount them as either hallucinations or experiences of the kingdom of darkness that is trying to deceive people by giving them experiences that are not in accordance with Scripture.
So, then, after all these examples and none completely answer your questions of knowing existence before or after death, I have to admit that my own reason for believing as I do in eternal life is simply this:
Because the Bible tells me so.

(It says there is "eternal life").
And so that brings up the question of whether or not the Bible is telling the truth, and that is too long of a discussion for this post.
