How I explained Bitcoin wallets to my 12 year old nephew. Am I correct?

This is how I explained it to my nephew, please let me know if I’m way off…

Imagine a universe with an infinite amount of planets, more planets than there are atoms in the entire universe we live in. Each of those planets is a BTC wallet.

When you generate a wallet, you’re essentially planting your flag on one of those planets and laying claim to it (you don’t create the planet - it already exists). You can store your digital assets right there on the surface of the planet, like treasure.

Your planet can only be found with your private keys/seed phrase - it’s like a map. A hardware wallet is basically a device that connects you directly to your planet.

It’s highly unlikely anyone will ever land on your planet by accident as there’s just so many of them out there.

There are space pirates who want to land on people’s planets to steal their treasure, but it costs them too much money to travel from planet to planet , so it’s unlikely they’ll ever find one with treasure on it. Instead, these pirates prefer to trick people into giving them their map (seed phrase). That’s why it’s important to never share it with anyone.

Anyone can look at the planets (wallet addresses) through a telescope and see what’s on each planet, but they can’t get there as they don’t have the map.

If you want to be extra-secure, you can use a passphrase wallet, which kinda creates an underground bunker on your planet. You can store your treasure in there, so if anyone were to ever land on your on planet, then they’d think it’s an empty one.

And to be even safer you can lay claim to multiple planets, or create multiple underground bunkers on the same planet. The options you have are limitless.

While nobody can access your planet, anyone can send funds there, kinda like your planet having an email address. This is known as your wallet address or public keys.

Is this a good analogy to make wallets more understandable for kids?
