If the Genesis account is true
"If the Genesis account is true, there was never a time when nothing existed. The atheist and the theist both agree that we cannot begin with nothing. Out of nothing comes nothing. If at one time nothing existed, there would not be anything now. However, something now is, therefore something has always been. That which has existed eternally is either a thing (matter) or a Being (God). This eternal existent is the cause of all else. Genesis one and naturalistic evolution both predict that it is contrary to reason and science to assume that at one time nothing existed."
