Scientists first make observations that raise a particular question. In order to explain the observed phenomenon, they develop a number of possible explanations, or hypotheses. This is the inductive part of science, observing and constructing plausible arguments for why an event occurred.
As indicated earlier, the Bible does not fix the age of the earth, contrary to the claims of Answers in Genesis. Historically, their claim comes from the work of James Ussher, Bishop in the Church of Ireland, from 1625 to 1656.
The Bible, however, is exceptional even among classical works. Although its written origins go back 3,500 years, it is still very much alive. It is by far the most widely circulated book on earth. Each year, some 60 million copies of the entire Bible or portions of it are distributed.
