The son of two Philadelphia teachers, David was raised to respect ancient wisdom and learned not to gloss over the scientific and mathematical clues in the Bible and other ancient texts. You may have seen him near the archives in Washington D.C., London, or the Vatican - or shared a bus to a pyramid or temple in Israel, Egypt, Turkey, Greece, or Mexico... At home in Pennsylvania he finds answers online - and celebrates every possible moment with his three inquisitive children, who remind him that we should never stop asking questions.
