There are more ways to shuffle a deck of cards than atoms on Earth
52! (52 factorial) is about 8 x 10^67 possible orderings, while Earth has roughly 10^50 atoms. Any well-shuffled deck is almost certainly in an order no deck has ever been in.
Claim source
The Wikipedia article on factorials confirms that 52! is approximately 8 x 10^67. This number of permutations exceeds the estimated number of atoms on Earth (~10^50), supporting the claim that a well-shuffled deck is likely in a unique order.
