Where do atoms come from?
Believe it or not, the atoms on Earth, including the ones in you and everything around you, came from outer space. Some atoms came from the original Big Bang that created the universe, but most came from exploding and colliding stars. www.acs.org/kids © American Chemical Society, 2017The Secret Science of Stuff Atoms, Page 3
