Earth was not around at the beginning—the universe began without us some 10 billion years earlier than Earth. The universe started out with only two elements, hydrogen and helium gas, which formed stars that burned these elements in nuclear fusion reactions. Generations of stars were born in gas clouds and died in explosive novas. The conditions in those novas produced the heavier elements we have with us today.
