"You can't tell anyone with a straight face that a quasar that's visible 2.4 billion light years away is only 6,000 years old."

But, it wasn't 2.4 billion light years away 6,000 years ago. It started from the exact same spot all quasars did when nothing exploded and became everything.

But, it wasn't 2.4 billion light years away 6,000 years ago.

If that were the case, then the quasars should appear less than 6,000 light years away, even though they're now 2.4 billion light years away. Unfortunately for your side, they don't.
