There are many who have sought out to prove or disprove the Bible - many have done it very honestly, perhaps the most thorough of which was is former non-Christian Dr. Josh McDowell whose deep honest and critical investigation into the claims of the Bible led him to believe it was true. Him and his son have compiled their findings in their written work through online articles (some linked below), and more of the entirety of their findings in 2 of their books (also linked below) titled "More than a Carpenter" (a more abbreviated investigative study) and the much longer and more in depth "Evidence that demands a verdict".
