Moving the goalposts is a logical fallacy in which the arguer changes the original claim without acknowledging the changes have been made. The arguer also does not respond directly to the evidence presented against his or her original claim.
Similar efforts have been undertaken with the Bible. This varies from person to person but similarly it has generally moved from the inviolable word of god, to an accurate historical account, to a collection of myths mixed in with a bit of history. Attempts to hang onto the tattered remnants of false hopes and beliefs even though those beliefs have no resemblance to the original position of any given individual.
Even though the original premise utterly collapsed years ago people still hang onto the tattered remnants of belief. This is based on the goalpost that now only requires the Bible (or Koran if you prefer) to be a morality tale. So even though the apologists are trying to prove a very different hypothesis than they were years ago the quest is somehow still valid. I would argue that the game ended the first time the goalposts moved. What has actually happened over the last several decades is the equivalent of not only moving the goalposts down the field but planting it in a different country and using it for a different game.
