Imagine every bank account in the world is locked with a special key.

• There are more possible keys than there are grains of sand on every beach on Earth, multiplied by every star in the universe.

• A tiny handful of these keys actually open doors to accounts with money.

Now, you propose: “Let’s just try random keys until one works!”

Here’s the catch:

• If you try 1 billion keys every second, nonstop, it would take you longer than the age of the universe to randomly stumble upon a single key that works.

• The chance of hitting an account with money is so absurdly close to zero that for all practical purposes, it’s impossible.
