We have good a priori reason to think that:
- If God exists, persons exist forever.
Our earthly life is very short, then. At most about a hundred years. Which is 0% of eternity. And by (1), we have good reason to think that if God exists, there is infinitely more later.
It is not that surprising that there is evil in a very good existence if the evil occupies only a small portion of the existence. And 0% is a small portion. Moreover, if we were to guess where the evil might be met with, the beginning of existence would be a reasonable guess. For improvement is much better than decay. And while we cannot be self-existent like God, being in some way the co-authors of our goodness is a great value. But that requires the possibility of not being good. And makes plausible the actuality thereof.
