Chaos
Chaos: from the Greek khaos: an abyss, gaping void.
     1) In Greek mythology, the total absence of time and space from which came all things - material and spiritual. Chaos  is the first of the Protogenoi and the god of the air. Later on Chaos was described as an original state of existence from which the first gods appeared. In other words, the dark void of space. It is the source of what the Ancient Greeks considered the four elements: earth, air, water and fire. For example, when a log is burned, the flames were attributed to the fire in it, the smoke the air in it, the water and grease that come from it were supposed to be the water, and the ashes left over were the earth.  In ancient Greek, it means "gaping void",  In the Pelasgian creation myth, Eurynome rose out of  Chaos and created all things.  The idea is also found in Mesopotamia and is associated with  Tiamat,  the 'Dragon' of Chaos, from whose dismembered body the world was formed. Genesis refers to the earliest conditions of the Earth as "without form, and void", a state similar to chaos
     2) The primordial state of disorder out of which the supreme being created the universe. 
     3) Some teachers say that Chaos is that which cannot be comprehended and thus equate Chaos with Nothing.  It is Chaos (that which cannot be understood) that produced Logos (that which can be understood)
