The things that we didn’t know, we thought God did, and now we’re learning how it happened, like the formation of planets and stars and The Big Bang and evolution and so forth. We thought God created the earth and the sun and the moon, and now we find out that it was just gravity. That’s all it was. Gravity.
I may make a more detailed explanation starting with the big bang and the formation of hydrogen and helium. Do you know why Big Bangs happen? Because they can.
