Here are some quotes from university websites by scientists who know that the universe had a beginning:
- "Scientists generally agree that "the Big Bang" birthed the universe about 15 billion years ago." Tom Parisi, Northern Illinois University
- "As a result of the Big Bang (the tremendous explosion which marked the beginning of our Universe), the universe is expanding and most of the galaxies within it are moving away from each other." CalTech
- "The Big Bang model of the universe's birth is the most widely accepted model that has ever been conceived for the scientific origin of everything." Stuart Robbins, Case Western Reserve University
- "Many once believed that the universe had no beginning or end and was truly infinite. Through the inception of the Big Bang theory, however, no longer could the universe be considered infinite. The universe was forced to take on the properties of a finite phenomenon, possessing a history and a beginning." Chris LaRocco and Blair Rothstein, University of Michigan
- "The scientific evidence is now overwhelming that the Universe began with a "Big Bang" ~15 billion (15,000,000,000 or 15E9) years ago." "The Big Bang theory is the most widely accepted theory of the creation of the Universe." Dr. van der Pluijm, University of Michigan
- "The present location and velocities of galaxies are a result of a primordial blast known as the BIG BANG. It marked: THE BEGINNING OF THE UNIVERSE! THE BEGINNING OF TIME!" Terry Herter, Cornell University
- "That radiation is residual heat from the Big Bang, the event that sparked the beginning of the universe some 13 billion years ago." Craig Hogan, University of Washington
- "Most scientists agree that the universe began some 12 to 20 billion years ago in what has come to be known as the Big Bang (a term coined by the English astrophysicist Fred Hoyle in 1950." University of Illinois
- "The universe cannot be infinitely large or infinitely old (it evolves in time)." Nilakshi Veerabathina, Georgia State University ()
- "The universe had a beginning. There was once nothing and now there is something." Janna Levin, Department of Applied Mathematics and Theoretical Physics at Cambridge University
- "Today scientists generally believe the universe was created in a violent explosion called the Big Bang." Susan Terebey, Department of Physics and Astronomy, California State University Los Angeles
- "Evidence suggests that our universe began as an incredibly hot and dense region referred to as a singularity." Stephen T. Abedon, Ohio State University
- "A large body of astrophysical observations now clearly points to a beginning for our universe about 15 billion years ago in a cataclysmic outpouring of elementary particles. There is, in fact, no evidence that any of the particles of matter with which we are now familiar existed before this great event." Louis J. Clavelli, Ph.D., Professor of Physics, University of Alabama
- "Now, after decades of observing and thinking, we have come to answer confidently the question of the origin of our universe... with what is known as the "big bang"." Yuki D. Takahashi, Caltech
- "The theory is the conceptual and the calculational tool used by particle physicists to describe the structure of the hadrons and the beginning of the universe." Keh-Fei Liu, University of Kentucky.
- "The three-part lecture series includes: "How the Universe Began," "The Dark Side of the Universe: Dark Matter and Dark Energy" and "Cosmic Inflation: The Dynamite Behind the Big Bang?" (Lectures by Michael S. Turner, Bruce V. and Diana M. Rauner at Penn State University)
- "Travel back in time to the beginning of the Universe: The Big Bang" Douglas Miller, University of Arizona
- "Beginning of the Universe 20.0 billion yr ago" Charly Mallery, University of Miami
- "At the beginning the universe was extremely hot and dense (more about this later) and as it expanded it cooled." Syracuse University
- "THE UNIVERSE AND ALL OF SPACE ARE EXPANDING FROM A BIG BANG BEGINNING" Center for Cosmological Physics, University of Chicago
- "Gamow realized that at a point a few minutes after its beginning, the universe would behave as a giant nuclear reactor." Valparaiso University, Department of Physics and Astronomy
- "I'll also include what the time is since the creation of the Universe, and an estimate of the temperature of the Universe at each point." Siobahn M. Morgan, University of Northern Iowa.
- "The Universe is thought to have formed between 6-20 billion years ago (Ga) as a result of the "Big Bang" Kevin P. Hefferan, University of Wisconsin-Stevens Point
- "The dominant idea of Cosmology is that the Universe had a beginning." Adam Frank, University of Rochester Department of Physics & Astronomy
- "The hot dense phase is generally regarded as the beginning of the universe, and the time since the beginning is, by definition, the age of the universe." Harrison B. Prosper, Florida State University
- "One of the major hypotheses on which modern cosmology is based is that the Universe originated in an explosion called the Big Bang, in which all energy (and matter) that exists today was created." Eric S. Rowland, UC Santa Cruz
- "Together with Roger Penrose, I developed a new set of mathematical techniques, for dealing with this and similar problems. We showed that if General Relativity was correct, any reasonable model of the universe must start with a singularity. This would mean that science could predict that the universe must have had a beginning, but that it could not predict how the universe should begin: for that one would have to appeal to God." Stephen W. Hawking "Origin of the Universe" lecture
In light of these facts we can logically infer the following :
-  Since the universe had a beginning, it also had a first cause.
A first cause for the universe had to be adequate to the effect ie. the cause had to be strong enough to create the universe, time and all that is in it.
 It had to have been created from nothing since it did not create itself. To say it was created from something (already existant matter & energy) is to say that it existed before itself which is absurd.
The only conceivable, adequate cause is some power existing without the universe
 Any such power must be metaphysical - beyond mere matter and energy.
The power must be a supernatural, all-powerful and super intelligent god being.
That a supernatural being is necessary is evident since super intelligence is required to create such an ordered universe with such strict physical laws and finely tuned cosmological constants.
Intelligence pre-supposes a thinker or a mind. Super intelligence pre-supposes a super mind. The very size & nature of the universe requires that the creative power behind it be omnipotent.
Intelligence pre-supposes consciousness, will and purpose. So this First Cause has personality and therefore is a conscious being with both thought and will and purpose. It is not random but ordered.
Put the 2 together : omnipotence + omniscience = God as descibed by certain "religions" throughout the world. God as all nations in all history have believed exists based on the evident design displayed throughout all nature.
Yes Virginia, there is a God.
