The theory of evolution upon which all Atheism hangs its proverbial hat cannot be proven. But now we know, based on the greatest scientific equations of the greatest scientific thinkers in the world, that the world was created in six 24-hour days. Our universe is expanding and as it expands, time elongates. In this universe time moves according to your perspective of it or the point from
which you observe it. What God did in the beginning is six 24-hour days from that point in time, but is measured differently from our point in time.
Based on the current scientific knowledge the universe is a little over 15 billion years old and only about 6000 years old at the same time. It’s all a matter of perspective. Are you measuring from the beginning when time was very condensed or from today when the universe (space and time) have continually expanded?
