The universe is finite.

If the universe is infinite, every permutation of every scenario, regardless of how unlikely it is, has played out and is playing out currently.
In an infinite universe where infinite monkeys type on infinite keyboards, one of them has just finished typing the complete works of Shakespeare.
Again!
How lucky we are indeed to exist on a planet in this 'infinite' universe where exactly that happened! His name, outrageously coincidentally, was also Shakespeare!
This is also true of fish.
On bicycles.
In an infinite universe, a fish has also just finished typing the complete works of Shakespeare on a bicycle, and he, she or it wasn't the first. Who said bicycles were useless to fish?
So my point is something like this:
If our little planet of lowly numbskulls has managed to create a machine which has the very slimmest of chances of destroying the planet or maybe even the universe, then the universe is finite.
Because if there is even the slightest kazillionth of a chance of that machine, or any other of infinite possible machines, designed and operated by infinite fish or monkeys or any inconceivable anything ever, then, however small the chances are above zero that the universe could be destroyed by it, the universe has been destroyed by it. And it hasn't.
Has it?
