In the 1800's, John Dalton was the first to propose the idea that all matter is made of tiny pieces called atoms. Today we call this "the atomic theory." Since it is a theory it may sound like scientists are not sure about it, but a scientific theory is an idea that has a lot of evidence that many scientists have gathered over a long time.
