Correct, the young earth creationist movement is itself pretty “young” and is distinctly a minority within Christianity. Of course, they will respond that their belief is the True Doctrine and everyone else is an infidel. Nothing new there.
Yeah, a really young movement, like, no older than the Bible itself, huh? Also besides Bishop Ussher, who calculated the 4004 BC biblical chronologies from Adam and Eve thru Jesus Christ, we also have the #1 scientist of all time, Sir Isaac Newton hisself, who also believed the literal Genesis account and calculated the ages too.
