Since the birth of the universe, it has continuously evolved. Because of this evolution, the night sky is filled with brilliant celestial bodies of all kinds. Because of this evolution, life is abundant and diverse.
Today, in addition to hydrogen, the universe contains a vast array of elements. Hydrogen and the other elements it produces are neatly arranged in their respective places in the periodic table.
After the Big Bang, only a portion of the hydrogen in the universe formed stars, not all of it. The hydrogen that initially did not form stars later coalesced to create new stars—the Sun is one such late-born star.
Among the countless celestial bodies in the universe, there exists one small planet called Earth—our home. On this planet, non-living matter eventually evolved into the first primitive life forms, which in turn evolved into the complex living beings we see today, including humans.
Non-living and living things together form the vibrant and dynamic Earth—an isolated vessel in the universe, a paradise for life.
Our bones, organs, muscles, fat, and hair; the food we eat, the water we drink, the tools we use; even our planet Earth itself—aside from hydrogen, all other elements originate from long-extinct stars that once shone in the distant past.
