Just watching a science program about the moon, they were trying to calculate the age of the moon by observing the difference between new and old craters.
New craters have obvious radiating blast marks and no smaller craters in or around the larger craters.
Older craters have been heavily covered in smaller impact craters and are quite deformed.
It is hard for me to imagine this random pattern of so many craters on the moon to be "Created" in this manner in just 6,000 years :-)
Of course as the gospel of the FSM says "The FSM has done things like this to deliberately confuse scientists" but back to the real world I wonder how fundies would explain this ?
