they didn't build until after they relocated there,you need to go back and read the post a little slower, and imagine all the earth changes going on within that first week...it would have taken a while for Atlantis to freeze over into Antarctica but not for the former ice around the former pole at Giza and the surrounding areas and the former south pole to melt..ice melts way quicker that it takes to form layer over layer,year after year...go to google earth and put Giza at the very top then spin the globe slowly without a tilt and remember the oceans would have been lower because more land around Giza would have supported more water locked up as ice...the equators would have been different too...the oceans would have rose, then started receding some as the ice started to reform at the new poles at the new tilt year after year,layer by layer..as i believe our new heaven and earth was formed when the moon was captured in orbit and changed the tilt and poles and equator and causing varying seasons by tilt instead of seasons by latitude...
