Randman, read the following argument:
There are dings in the side of my car door, even though there is no car parked next to mine. Therefore, this is positive evidence for the existence of magical Door Ding Gnomes! They appear from thin air, when they think no one is around, with little picks and hammers, to put dings into people's car doors.
Can you develop an argument for Intelligent Design that is better, more reliable for biology - than my Door Ding Gnome Theory is for explaining car door dents?
