Silly grant pimping rabbit. We are here because God made us.
We need to understand what happens to the solar system during its 250 million year long orbit around the galactic center. It might help understand why we have mass extinctions, ice ages and climate change.
When our ego get’s in the way of understanding, we will pay the piper sooner or later.
Thus the questions, how did He do it, and why did He do it they way He did?
I think God wants us to seek these mysteries. Besides, physics and mathematics are fun.
