There's something about night and day, and life and death, but animals are also mentioned a lot of times in the bible, showing up in places of desolation, or after destruction, or after the humans left the place, suddenly they would show up.
When we believe that God is Father, we also believe that such a father's hand will never cause his child a needless tear. We may not understand life any better, but we will not resent life any longer.
