The quantum model of universe is an attempt to purge the Big Bang of its creationist implications. Supporters of this model base it on the observations of quantum (subatomic) physics. In quantum physics, it is to be observed that subatomic particles appear and disappear spontaneously in a vacuum. Interpreting this observation as matter can originate at quantum level, this is a property pertaining to matter, some physicists try to explain the origination of matter from non-existence during the creation of the universe as a property pertaining to matter and present it as a part of laws of nature. In this model, our universe is interpreted as a subatomic particle in a bigger one.

However this syllogism is definitely out of question and in any case cannot explain how the universe came into being. William Lane Craig, the author of The Big Bang: Theism and Atheism explains why:

A quantum mechanical vacuum spawning material particles is far from the ordinary idea of a "vacuum" (meaning nothing). Rather, a quantum vacuum is a sea of continually forming and dissolving particles, which borrow energy from the vacuum for their brief existence. This is not "nothing," and hence, material particles do not come into being out of nothing. 1

Ancient Greek thinkers imagined that all bodies consisted of tiny particles called atoms. They maintained that these atoms shaped the universe and all living things, without intention or direction and without being subjected to any conscious intervention. According to this belief, matter was timeless and eternal, and nothing beyond matter could exist. Supernatural events that intervened in entities’ behavior and altered their structures was sheer superstition, unacceptable. All axioms and principles were based on the assumption that matter was an absolute reality.

Since matter was eternal, the universe must be eternal as well, and that idea served as the foundation of atheism. If the entire universe had existed for all time, then according to the perversion of materialist belief, it was impossible for matter and the universe to ever have been created.

According to materialists, the universe was eternal, and therefore, there was no purpose or special creation in it. Materialists imagined that all the balances, equilibrium, harmony and order in the universe were solely the results of chance. They claimed that everything came into being as the result of unconscious atoms assembling at random. And no matter how much complexity, balance and magnificent regularity exhibited by the external world, these were still the result of purposeless coincidences.
