Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.

Who created atoms?

The idea that everything is made of atoms was pioneered by John Dalton (1766-1844) in a book he published in 1808. He is sometimes called the "father" of atomic theory, but judging from this photo on the right "grandfather" might be a better term.

Are atoms being created?

The short answer is yes, atoms are being created all the time. ... It's called nuclear fusion and basically involves mashing protons and neutrons together to form new atoms-- some hydrogen, some helium, some lithium, etc, all the way up to iron. Another way to make new atoms is through a supernova.
