Neil DeGrasse Tyson is an astrophysicist and director of the Hayden Planetarium in New York City.
What he’s talking about in this video is the fact that all the matter that in the universe including planets, trees and people are made up of light or heavy atoms. Light atoms are smashed together inside stars and then sprayed out into the universe to get smashed together in bigger stars into bigger atoms. Then, by and by, they combine in just the right way and Earth appears and animals appear and here we all are.
