Why is kanada associated with the atom?

The sage kanada, who lived in the 6^th century BC, was the world’s first proponent  of the ‘atomic theory’. He stated that the atom- or paramanu- is indivisible, and that the world is made up of atoms. He has classified all the objects of creation into nine elements earth, water, light, wind, ether, time, space, mind, and soul. According to him, every object of creation is made of atoms. Kanada added that there are a variety of paramanu that are as different as the different classes of substances. Each paramanu has a peculiar property which is the same as the class of substance it belongs to. Kanada spoke of the tendency of atoms or paramanu to combine together to form what we now call molecules. Kanada also put forward the idea of chemical change, which he said is caused by heat. Kanada was a genius, philosopher, and the pioneer of the atamic theory.
