The car in their driveway DID have a maker - a factory they can go see for themselves, if they have any doubts.
Whether or not humans had a maker is a matter of faith. One can trust or believe, but one can’t know.
What’s wrong with admitting you don’t know something that you don’t know?
I won’t fault you for claiming to know something beyond the limits of your knowledge.
You shouldn’t fault me for admitting some things are beyond the limits of my knowledge.
Those who live by faith absolutely believe in God and their is NO doubt. There is a question to ask yourself though...do you believe IN God or do you BELIEVE God? Only you can answer that question honestly.
