Democritus
Democritus was a Greek philosopher who started research on atoms and matter 2400 years ago. His theory was matter could not be divided forever eventually you would be at the smallest piece possible. And his theory was ignored for 2000 years because of Aristotle's theory.
This is what they thought the atom looked like |
Aristotle
Aristotle believed in the four elements. Earth, water, fire, and air and he showed this by burning a log. The log is earth the fire is fire and the smoke is air and he put the fire out with water. And the people back then believed him because it was easier to understand and they could see it with there own eyes.
