We don’t have the technology or equipment to move those giant blocks today, how exactly did they do it? The supposed river would not have accomplished what they are trying to sell.
Are you related to the posters yesterday who were saying the moon landing was faked? Why do you say such crazy stuff? “We don’t have the tech today to move blocks?” That’s just crazy talk.
Or the giant statues that had to be cut into chunks to be moved when the Aswan dam was built. Apparently Egyptians without modern tech could make those statues and move them many miles somehow. And how the faces are symmetrical to within a mm using hand tools is also a mystery. Not to mention the very apparent rotary tool marks. Pretty clever use of bronze tools, eh?
