Tornados don't always skip over churches.
The natural law dictates that we will be born, live and then die. The body will be destroyed. The energy dissipated, the soul, will be judged.
The atoms are still there. When a tree sheds its leaves, the leaves go into the ground where the tree, or other plants, then take those nutrients and reuse them.
The same when animals die, they either get eaten or they go into the ground and become food for something or other.
Do things get destroyed, yes and no, the atoms don't get destroyed, they can change and become something else. This is life.

You have defined part of the Natural Law and you don't even realize it.
Ecclesiastes 3:2New International Version (NIV)
