It was so appropriate that after we've been discussing this topic, my 11 year old asked me if I knew about the big bang theory. I told him that I did.
I asked if he knew what evolution was, and he knew some of it.
I told him there were people that didn't believe in evolution or the big bang theory, and they believed that God created the earth in 6 literal days.
He then asked what I believed. I said I didn't know what was the truth, but I knew that God started it all.
