YoungEarth Creationism is unanimously rejected by the scientific community. Deep time and the billion year age of the Earth are not pet hypotheses of "evolutionists", a postulated faction of godless maverick scientists — they are uncontroversial and widely accepted facts, with consistent evidence from multiple disciplines. In fact, deep time and an old Earth aren't even part of evolution—they're questions .
