No, don’t you understand? Newton discovered the laws of gravity and gravity is observable. Now, Newton believed in intelligent design and (some might say) was a Christian.
So it logically follows that if you believe in gravity that you are a creationist!
(Natural selection sarcasm mode)
"I believe in natural selection, but not in Darwin's theories"
is like saying,
"I believe in honesty, but there's nothing wrong with stealing".
Logical contradiction.
