I want to know the answer to the following question:
Who first introduced the idea that matter is made of atoms?
All the background I'm provided with is that "6th-century BCE pre-Socratic Greek philosophers Thales of Miletus and Xenophanes of Colophon were the first in the region to attempt to explain the world in terms of human reason rather than myth and tradition, thus can be said to be the first Greek humanists.". Is that enough to answer the question?
Answer: no
