How can two singers sing the same song in the same key still have distinguishable voices?

This is actually question my daughter posed and I’m pretty stumped. She asked how, if two people with (let’s say) perfect pitch sing a song, how is it possible that we can still tell who is singing when the notes would be identical?

Note: I know absolutely nothing about music, but figured this was the best place to ask for her.

Edit: Wow, many of these answers are incredible! I had no idea this would receive such in depth and thoughtful feedback. I have learned a huge amount. I was not exaggerating above when I said I know nothing about music (I don’t even know what pitch is – just quoted my daughter on that) and I’m grateful to those of you who took the time to help me learn.

So basically everyone has vocal chords but they’re all shaped a little different. Because of that little difference it makes the frequencies slightly different. And our bodies are also different so the way the sound resonates in my mouth before it comes out is different.
