If reincarnation is true, life would be loving awesome. Commit Self Delete, then be reborn.
What if reincarnation took a really, really, long time to take place?
If you were reincarnated on the same planet, it would be so disorientating to go from one timeframe of knowledge to another one however many years later.
And it would probably be even more disorientating if you were reincarnated as some other lifeform in the universe, or what if you became the first organism somewhere else in the universe?
Life spent continuously splitting your single-cell self?
Or as some form of amoeba?
And just imagine if you kept your consiousness during all of that. You'd lose your sanity, probably after a couple of reincarnations. But then you have to wonder, how could anyone be sane then, if we're all just repetitively repeating consiousness's. It would be a very messed up world.
I guess if reincarnation were the case, you'd have to hope you didn't retain your consiousness, just because of all the understanding and renewal you have to go through. Life would also be extremely boring, and probably painful by the end, since you can never stop, and you just see too many things to carry on, yet nature makes you.
