“For we’ve science to guide us, thank god!”

According to Wikipedia, Richard Dawkins, in addition to his renown as an evolutionary biologist, is a prominent English atheist intellectual and critic of creationism. He frequently points to religion as willful ignorance that detrimentally attempts to fill the blanks in human understanding of the universe with ideas that lack critical thinking, reason and evidence-based inquiry.
