How were the ideas of Aristotle and Democritus similar to the alchemists'?

The ideas of Aristotle and Democritus were on a similar basis to the alchemists.

Explanation:

Aristotle believed that all matter was made from four elements: earth, air, fire, and water. Democritus was the first person to realize that if something was cut in half continuously it can never be broken down completely. Democritus called the units that could not be broken down atoms. Early alchemists believed and based their works on the notion that atoms could be rearranged into making new elements. All three of their ideas more or less work with atoms and elements.
