ELI5: How is every person's voice unique?

The title says it all.

I was just wondering how it's possible that every single person's voice is so unique to each other? It's all the same systems, the same organs, so how does everyone sound so different? I understand it to a certain extent, but would like to have it explained!

Same organs but all shaped differently. The size of your voice box, thickness of your vocal chords, length of your throat, size and shape of your mouth, size, shape and positioning of your tongue, even your sinus passages, all play a role in how your voice sounds. And all of that is different for everyone.
