Confidence in the repeatability of observed behavior != theory explaining that observed behavior.
Being 99.99999999999999% certain that dropping a rock will result in the rock falling does nothing to explain how gravity causes the rock to fall in the first place.
Sorry you came in late... I would have like to have visited with you. Gotta go to lunch. Have a great day. I'm going to. I'm going to spend my lunch hour dropping rocks now that I know there's a chance that one might not fall when I let go.
