No one was there when the universe began so we cannot say with complete certainity how our world began. The One who created it all was there and He has told us how He did it! Hebrews 11:3 describes that while there is faith involved, there is also evidence that can be examined from which reasonable conclusions can be drawn (Hebrews 11:1). There is also much faith involved in cosmology when trying to describe our universe, specifically what is now called dark energy and dark matter, which comprises 95% of our univese. It cannot be seen, examined, measured or proved. Only the effects can be observed. It is all based upon faith and observation of the expanding universe and the bending of light. Creation by a infinite, powerful, wise and unseen God or evolution that appeared from nothing and a series of radom events over time both take a large leap of faith. Are you stepping into the dark matter or are you walking in the light of God?
