Most bitcoin explanations are cringe af.
Listen to me. 
Bitcoin is a database, so is fiat. Bitcoins’ database is 1. decentralised and 2. synchs into a consensus in a novel as surprisingly robust way, 3. allowing any tx within its rules without censorship or ways to change the db in anyone’s favor. 4. It’s finite supply, this isn’t technological, it was a choice.

Because of all of this, some people use Bitcoin as money all over the world.

That’s it.
