In the beginning God created the heaven and the earth.
This is the first verse of the Bible, it is important to note that God is assumed to exist and he is designated as the first cause from which all affects come. Mentioned in this verse are the three main components of the universe space (the heaven), mater (the Earth), and time (the beginning).
In physics, relativity theory shows that space, matter (energy) and time are interrelated parts of the universe such they can not exist separately. It also shows that time is an integral property of the universe that can have a beginning. Furthermore the beginning of time must coincide with the beginning of space and matter and Genesis 1:1 is consistent with this.
