So what are the odds that the stones were in a much older structure and the glacier destroyed the place and pushed the stones to where they were re-used by the builders of Stonehenge? I mean, Anthony West has a credible theory that the foundation blocks (carved blocks set under the pyramids and Sphinx) under the Giza plateau are perhaps hundreds of thousands years old, matching the age of blocks at Obiados (sp?).
Hoagland is favoring that idea. The foundations of the pyramids would be 200,000 years old. We ought to keep that idea around since it would hard to dismiss outright without putting unnecessary limits on our speculation.
