Dex I didn't reference any of that, what I did reference is his view as a machinist. The vids have more to do with Brein Forester than Chris Dunn. Turn the sound down to avoid getting tangled up in the (unproven) theories and just look at the video and (you) explain how all the 'construction' could be accomplished with copper chisels. The artifacts need some better explanation than what is currently proposed, such as the weathering on the Sphinx when a geologist with a 17 page resume says it was caused by rain then that view should bot be discarded just because he doesn't have the rest of the story.
In that light, what do you consider to be 'contrary evidence' when the when all theories are based on a hypothetical theory that has no solid proof.
Science shows that North Africa once had rivers flowing all through it yet the 'evidence' always shows that during an ice-age the desert regions always stay desert regions and the green belt that is between the ice and the (current) band of deserts that circle the globe remain just as they are and it is the green belt that disappears when that is false for North Africa so it would also be false for the American South-west and for Mongolia as well, they would be as green as North Africa was at that time.
I don't have a problem thinking the Nile was a larger river back then and today it is a trickle compared to what it was back then, a rise of only 50 ft would have it at the paws of the Sphinx, nor do I have a problem thinking that the weather patterns back when the ice-caps were at their largest that to ocean level was 450 lower than it is today and with all probability that extra moisture would have changed the Dead Sea into a body of water that could host schools of fish. Just because nobody is currently promoting that doesn't mean the theory is 'out to lunch'. History shows that 'Scientists' and 'Academics' are notoriously slow on updating their 'beliefs' so it meshes with newer finds and updated theories based on those new finds.
Using the power plant theory just lets you reject his comments on tool marks and he is an expert on those, more than a little convient for you holding onto what you 'have faith in' as being supportive of what the 'facts' actually are.
