Modern science generally agrees with the belief that the universe had a beginning. Edwin Hubble was the first to publish data on this which was widely critiqued and overwhelmingly accepted. Except for a few skeptics, the “Big Bang” theory is still generally considered by science as the most plausible and realistic explanation for how the universe began.
One well known skeptic, Richard Dawkins, disagrees. He does not believe that life had a spontaneous beginning, and that ultimately reasons back to that the universe could not have had a spontaneous beginning, either. The simpler, most corroborated explanation is that the universe (and life) had a Creator. For some, though, the explanation has to be anything but God.

God exists whether or not men may choose to believe in Him. The reason why many people do not believe in God is not so much that it is intellectually impossible to believe in God, but because belief in God forces that thoughtful person to face the fact that he is accountable to such a God.
