So it’s possible. Might even have already happened. In fact, in the deck shuffle per second scenario there is a microscopic chance it happens each second.
It like trying to explain Mean time between failures. If it’s a million hours then there is 1 millionth of a chance per hour that the failure occurs.

Sure, there’s a roughly 8*10^57 chance that it’s happened.

Technically if you did this experiment in a classroom of 15 people it's possible 2 decks would be the same. However unlikely. Crazy isn't it.

That doesn't necessarily follow, right? It's not enough to know the size and age of the universe, you also have to know the chance of atoms moving that way. Of course, we live in a universe where that did happen, because, uh, that film exists. But that doesn't mean it's likely to happen ofc. It's like saying: given how many grains of sand there are on this beach, one of them must be an exact replica of the Taj Mahal down to the atom. When in fact, the number of possible arrangements of atoms in a grain of sand is vastly more than the number of grains of sand on the beach

But we know the number of grains of sand is finite. We don't know if the universe is finite.

True. All I was saying is we don't have enough information to know this

No, but every second there is a chance that just because of entropy, atoms fuse into a brain with the knowledge and memories that you have right now, so everything you have lived could perfectly be some atoms in line and that 10 seconds after it, they just move into another position

Not true. It’s unlikely that even something so seemingly simple as a deck of cards has, or ever will be, randomly shuffled in the same order. Ever.
There are 52! (factorial) possible random ways to order a deck of playing cards. That number is enormous - 8x10^67 (8 followed by 67 zeroes).
If every person on earth (8x10^9 people) shuffled a deck of cards once per second for the lifetime of the universe (4.16x10^27 seconds), no two decks would be the same. This would still be true if you ran the same calculation, but assumed there was an earth with 8 billion people around every star in the entire universe (1x10^24 stars) sitting there for 13.2 billion years shuffling cards every second.
