Some of these early life forms were archaea: an enigmatic third form of life only discovered in the 1970s. (The other two forms are bacteria and eukaryotes, the group that includes all animals, plants and fungi.)
Three-quarters of all matter in the universe is made up of hydrogen. The young Earth was also rich in hydrogen, thanks to fierce geological and volcanic activity.
Just as stars burn hydrogen to produce heat and light through nuclear reactions, life emerged by extracting energy from this simple molecule via chemical reactions.
