The evidence that the big bang was God's method of creation is compelling for many reasons. For instance, it reveals the very nature of God, just as Romans 1:20 says creation should. It doesn't just reveal God's character to those who already believe in him or to those who only look superficially at nature; it reveals the very nature of his character to those who study the universe in depth. It drives people to realize that the creator is a transcendent designer who cares for humanity. It leaves them truly without excuse because they have rejected the creator, not for the record of creation.
