The Bible (from Koine Greek τὰ βιβλία ta biblia "the books") is any one of the collections of the primary religious texts of Judaism and Christianity. There is no common version of the Bible, as the contents and the order of the individual books (Biblical canon) vary among denominations. The 24 texts of the Hebrew Bible are divided into 39 books in Christian Old Testaments, and complete Christian Bibles range from the 66 books of the Protestant canon to the 81 books of the Ethiopian Orthodox Church Bible. The Hebrew and Christian Bibles are also important to other Abrahamic religions, including Islam and the Bahá'í Faith, but those religions do not regard them as central religious texts.

The Hebrew Bible, or Tanakh, is divided into three parts: (1) the five books of the Torah ("teaching" or "law"), comprising the origins of the Israelite nation, its laws and its covenant with the God of Israel; (2) the Nevi'im ("prophets"), containing the historic account of ancient Israel and Judah focusing on conflicts between the Israelites and other nations, and conflicts among Israelites – specifically, struggles between believers in "the LORD God" and believers in foreign gods, and the criticism of unethical and unjust behavior of Israelite elites and rulers; and (3) the Ketuvim ("writings"): poetic and philosophical works such as the Psalms and the Book of Job.

Penn & Teller (Penn Jillette and Teller) are American illusionists and entertainers who have performed together since the late 1970s, and are known for their numerous stage and television shows. Their current Las Vegas show is an amalgam of illusion and comedy. Penn Jillette is a raconteur; Teller generally does not speak while performing, although his voice can occasionally be heard during their performance. They specialize in gory tricks, exposing frauds, and performing clever pranks. More recently they have become associated with atheism, scientific skepticism, and libertarianism, particularly through their television show Penn & Teller: Bullshit!.

Penn Jillette and Teller were introduced to one another by Weir Chrisimer, and they performed their first show together at the Minnesota Renaissance Festival on 19 August 1975. From the late 1970s through 1981, Penn, Teller, and Chrisimer performed as a trio called "The Asparagus Valley Cultural Society" which played in San Francisco at the Phoenix Theater. This act was sillier and less "edgy" than today's Penn & Teller act.^{[citation needed]} Chrisimer helped to develop some bits that continued, most notably Teller's "Shadows" trick, which involves a single red rose.

Clinton Richard Dawkins, FRS, FRSL (born 26 March 1941), known as Richard Dawkins, is a British ethologist, evolutionary biologist and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.

Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution and introduced the term meme. In 1982 he introduced an influential concept into evolutionary biology, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.

Dawkins is an atheist, a vice president of the British Humanist Association, and a supporter of the Brights movement. He is well known for his criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argued against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he described evolutionary processes as analogous to a blind watchmaker. He has since written several popular science books, and makes regular television and radio appearances, predominantly discussing these topics. In his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion—"a fixed false belief." As of January 2010 the English-language version has sold more than two million copies and had been translated into 31 languages.
