Ancient Ice Ages or Gigantic Submarine Landslides, Mainstream scientists present many challenges to creationists. One of the main geological challenges are the pre-Pleistocene ice ages, which group into four main periods of geological time: 1) mid Precambrian, 2) late Precambrian, 3) late Ordovician, and 4) late Paleozoic. Their evidence consists of hardened till-like rocks associated with other “diagnostic” features sandwiched between sedimentary rocks. How can an ice age occur in Flood sediments or, as some creationists believe, in pre-Flood sediments for the Precambrian cases? Davis Young in _Christianity and the Age of the Earth_, pages 90-91, considers pre-Pleistocene ice ages one of the main geological arguments against the Genesis Flood. In this compact book, the hypothesis of pre-Pleistocene ice ages is analyzed and challenged, and an alternative is presented: gigantic submarine landslides during the catastrophic Flood.
