The theory states that the Universe began 13 + Billion years ago as a single point. So it wasn't big and probably not much bang either. My question is this: Why does there have to be a science vs religion argument about this? You either believe in God and the creation or you believe that the Universe created itself from this singular point, although unknown as to how, and began expanding from there.
The way I see it, we don't have to believe in one or the other. If you believe in God, then you probably believe that He is all powerful and all knowing. He is the Supreme Being. So isn't it likely that He is the greatest scientist with the greatest scientific mind and understanding that is infinitely beyond our capacity to understand or imagine. In Genesis, God said "Let there be light and there was light." Why do some doubt that yes, it was actually God that created the "Big Bang" and from there expanded, organized, and created this wonderful, glorious Universe? It makes perfect sense to me. God is also the Greatest artist, inventor, physicist, scientist, astronomer, Geneticist, and Biologist, Geologist, Botanist, Organizer, CEO, etc. etc.
Why do we doubt? Why do we insist on putting limits on He who is the Greatest of All? Is it because we can't comprehend that there is a Being, a Divine Being, in charge out there that we can't find, see, or fully understand His majesty? We are infants in our understanding of His power and capability. His ways are higher than our ways. There are brilliant men in this world. There have been throughout history, and some can't believe in the existence of God because there is no proof. What if instead of the old adage "Seeing is believing", we change it to "Believing is seeing". Seeing, not with our physical eyes, but with the eyes of our understanding...our faith that grows and expands until it is a knowledge. If we are willing, we can allow our minds and hearts to be taught by a Higher, Perfect Source of all knowledge.
