Every last atom on this planet was either forged by nuclear reactions deep inside long dead stars, or was created by the birth of the Universe itself. That includes the atoms which make up every pebble, every oak tree, every lettuce leaf, and every human.
The Universe isn't merely some faraway thing which you only see when you look into the sky at night. It's also you.
You share that in common with everything you've ever seen, and everyone you've ever met.
@InvaderXan Not technically true ;) A lot were made by natural nuclear fission (which happens in the earth's core), and a few by humanmade nuclear fission or fusion even.
