Bill gates weighed in on this question a bit recently, I thought his comments were interesting:
"In a long, in-depth interview with Rolling Stone published last week, Microsoft founder Bill Gates said that while he agrees God could be a figment of mankind’s needy imagination, science cannot fully explain how the world came about.
Augustine (354-430) is generally considered to be one of the most important church fathers for Protestant and Catholic Christianity. He expounded a concept of human evil called original sin, which was further developed by Thomas Aquinas, Martin Luther, and John Calvin among many others. Augustine’s thinking was that there had been a fall of humanity after which every person is “born into sin,” or inherently evil.
