If God exists eternally and creates at least one universe, then he creates an infinite number universes

According to many religions, God has created the world, i.e., he has created our universe. The universes, that God creates, we will call local universes. Under Universe we will understand everything, i.e., all matter and energy that has existed, exists and will exist and outside of the universe there is nothing. The principal result of the present paper is as follows: if God exists eternally and creates at least one universe, then he creates an infinite number of local universes and the initial moments of these local universes are unbounded from below and from above on the time axis. The union of these local universes is the whole universe (Theorem 2.2). The above stated result is an addition to the basic situations about the creation of the world according to Roman Catholicism, Christianity and other religions. Furthermore, in the paper a review is done of some results in relation with the three fundamental open questions of cosmology of the universe as a whole, namely: 1) does time of the universe have a beginning, 2) is the universe infinite or not and 3) origin and development of the universe as a whole and not of its separate regions.
