There are a large percentage of Creationists who do NOT buy into the “young earth” narrative. (6,000 yrs. old)

People pretending to be able to age Creation by adding the “7 days” of Creation, to the lifespans in Begats, are kidding themselves.
Enlighten me as to why I am kidding myself. If you simply read the "begats", as you call them, and do a little arithmetic...
