well we have a couple of theories here:
1. We are a experiment of 'god' to see how long we last and what we do.
2. To life your live -> make new live -> die, in a un-ending repeated cycle
Now what I think myself (3)
3. To enjoy life, learn from it, pas that knowledge on, and unravel the question of live,
once we have done that we are either done with everything or unravel new questions
would you like to be able to live in reborn but without be able to catch or have pokes?
