The pyramids are books of stone and collectively they are The Book of Knowledge and thus they do contain information for us. And yes they were designed to last for the ages and yes there may be a message contained within this framework but to state that this enlightened people worried about storing food for themselves when the world was about to, or was undergoing, a shift of 6.5 degrees is ridiculous. In order to have built these structures as Gary and Scott claim they would have had to know about it maybe a hundred years in advance to give them time to build all the pyramids in question. If they knew it this early they would have known the severity of it as well. I just can't visualize the Ancient Egyptians just standing there while the waters displaced by this shift came crashing over them and then having the survivors going to the pyramids and getting their supper.
And to claim that the seeds and artifacts were symbolic is ... well it just doesn't cut it, at least with me.
