"The universe requires a cause, because (unlike God) it has not always existed, but had a beginning to its existence.
Science and philosophical
considerations show that the universe must have had a beginning.
The
cause of this beginning must be beyond the universe, and be powerful
enough to create a universe.
This evidence positively points to several
attributes the Bible ascribes to God (transcendence, omnipotence), and
to the Bible’s opening verse (In the beginning God created the heaven and the earth. Genesis 1:1)." CMI
