Robert Jastrow (a NASA scientist, astronomer, physicist, cosmologist, and agnostic) argues that the Big Bang is scientific evidence for the existence of God.
- “the essential element in the astronomical and biblical accounts of Genesis is the same; the chain of events leading to man commenced suddenly and sharply, at a definite moment in time, in a flash of light and energy…. The Hubble Law is one of the great discoveries in science; it is one of the main supports of the scientific story of Genesis.” ~ Robert Jastrow
- “Certainly there was something that set it all off. Certainly, if you are religious, I can’t think of a better theory of the origin of the universe to match with Genesis.” ~ Robert Wilson
When Albert Einstein developed his general theory of relativity in 1915 and started applying it to the universe as a whole, he was shocked to discover it didn't allow for a static universe. According to his equations, the universe should either be exploding or imploding. In order to make the universe static, he had to fudge his equations by putting in a facto that would hold the universe steady.
In the 1920's, the Russian mathematician Alexander Friedman and the Belgium astronomer George Lemaitre were able to develop models based on Einstein's theory. They predicted the universe was expanding. Of course, this meant that if you went backward in time, the universe would go back to a single origin before which it didn't exist. Astronomer Fred Hoyle derisively called this the Big Bang -- and the name stuck!
Starting in the 1920's, scientists began to find empirical evidence that supported these purely mathematical models. For instance, in 1929, the American astronomer Edwin Hubble discovered that the light coming to us from distant galaxies appears redder than it should be, and this is a universal feature of galaxies in all parts of the sky. Hubble explained this red shift as being due to the fact that the galaxies are moving away from us. He concluded that the universe is literally flying apart at enormous velocities. Hubble's astronomical observations were the first empirical confirmation of the predictions by Friedman and Lemaitre.
Then in the 1940's, George Gamow predicted that if the Big Bang really happened, then the background temperature of the universe should be just a few degrees above absolute zero. He said this would be a relic from a very early stage of the universe. Sure enough, in 1965, two scientists accidentally discovered the universe's background radiation -- and it was only about 3.7 degrees above absolute zero. There's no explanation for this apart from the fact that it is a vestige of a very early and a very dense state of the universe, which was predicted by the Big Bang model.
The third main piece of the evidence for the Big Bang is the origin of light elements. Heavy elements, like carbon and iron, are synthesized in the interior of stars and then exploded through supernova into space. But the very, very light elements, like deuterium and helium, cannot have been synthesized in the interior of the stars, because you would need an even more powerful furnace to create them. These elements must have been forged in the furnace of the Big Bang itself at temperatures that were billions of degrees. There's no other explanation.
So predictions about the Big Bang have been consistently verified by the scientific data. Moreover, they have been corroborated by the failure of every attempt to falsify them by alternative models. Unquestionably, the Big Bang model has impressive scientific credentials . . . . Up to this time, it was taken for granted that the universe as a whole was a static, eternally existing object . . . . At the time an agnostic, American astronomer Robert Jastrow was forced to concede that although details may differ, “the essential element in the astronomical and Biblical accounts of Genesis is the same; the chain of events leading to man commenced suddenly and sharply, at a definite moment in time, in a flash of light and energy”.... Einstein admitted the idea of the expanding universe “irritates me” (presumably, said one prominent scientist, “because of its theological implications”).
This should be put in bullet points for easy memorization:
• Albert Einstein developed his general theory of relativity in 1915;
• In the 1920s using Einstein's theory, a Russian mathematician and Belgium astronomer predicted the universe was expanding;
• In 1929, Hubble discovered the Red-Light shift showing that galaxies are moving away from us;
• In the 1940's, George Gamow predicted a particular temperature to the universe if the Big Bang happened;
• In 1965, two scientists discovered the universe's background radiation -- and it was only about 3.7 degrees above absolute zero.

Let’s consider a basic question: Why does the natural world make any sense to begin with? Albert Einstein once remarked that the most incomprehensible thing about the universe is that it is comprehensible. Why should we be able to grasp the beauty, elegance, and complexity of our universe? Einstein understood a basic truth about science, namely, that it relies upon certain philosophical assumptions about the natural world. These assumptions include the existence of an external world that is orderly and rational, and the trustworthiness of our minds to grasp that world. Science cannot proceed apart from these assumptions, even though they cannot be independently proven. Oxford professor John C. Lennox asks a penetrating question, “At the heart of all science lies the conviction that the universe is orderly. Without this deep conviction science would not be possible. So we are entitled to ask: Where does the conviction come from?”" Why is the world orderly? And why do our minds comprehend this order? Toward the end of The God Delusion, Dawkins admits that since we are the product of natural selection, our senses cannot be fully trusted. After all, according to Darwinian evolution, our senses have been formed to aid survival, not necessarily to deliver true belief. Since a human being has been cobbled together through the blind process of natural selection acting on random mutation, says Dawkins, it’s unlikely that our views of the world are completely true. Outspoken philosopher of neuro-science Patricia Churchland agrees:
The principle chore of brains is to get the body parts where they should be in order that the organism may survive. Improvements in sensorimotor control confer an evolutionary advantage: a fancier style of representing [the world] is advantageous so long as it… enhances the organism’s chances for survival. Truth, whatever that is, takes the hindmost.
Dawkins is on the right track to suggest that naturalism should lead people to be skeptical about trusting their senses. Dawkins just doesn’t take his skepticism far enough. In Miracles, C. S. Lewis points out that knowledge depends upon the reliability of our mental faculties. If human reasoning is not trustworthy, then no scientific conclusions can be considered true or false. In fact, we couldn’t have any knowledge about the world, period. Our senses must be reliable to acquire knowledge of the world, and our reasoning faculties must be reliable to process the acquired knowledge. But this raises a particularly thorny dilemma for atheism. If the mind has developed through the blind, irrational, and material process of Darwinian evolution, then why should we trust it at all? Why should we believe that the human brain—the outcome of an accidental process—actually puts us in touch with reality? Science cannot be used as an answer to this question, because science itself relies upon these very assumptions. Even Charles Darwin was aware of this problem: “The horrid doubt always arises whether the convictions of man’s mind, which has developed from the mind of the lower animals, are of any value or at all trustworthy. Would anyone trust the conviction of a monkey’s mind, if there are any convictions in such a mind?” If Darwinian evolution is true, we should distrust the cognitive faculties that make science possible.
