This is because they all believed in God and in his Word in respect to the world around them. Yet, many scientist of old and today, make it their calling in life to prove that there is no God and the world which we know is just a gigantic cosmic accident ... which as hard as they may try, is an impossible position to defend.
Hebrews 11:3
"Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear."
