Someone posted the above vid somewhere on GHMB and I've got to thank that person. How anyone, who takes the time to watch vids like this, comes away without having changed their views on very ancient (advanced) civilizations is interesting. Same building techniques with massive stones all over the world. The pyramid at the 22:20 min mark - just one example of many.
The evidence is all around us.
You have certainly kept your composure much longer than I would have with some of the replies/posters. Chris Dunn has video'd his attempts to cut granite with copper tubing and abrasives (sand I believe)...complete failure. He comes right out and states the obvious which is that it can't be done even with iron chisels etc.. Feed rates mean something to engineers but not to Egyptologists or those who have been mesmerized by what they have been told by the same.
Like you, I"ve been at this for a very long time - searching for answers which don't involve fairytales of oxen and copper...
I've come to the conclusion that we will likely never know the true history of our planet. As per Michael Cremo, some of these ruined cities/walls could very well be millions of years old and, as is pointed out by the woman presenting in the above, it seems like many of these ancient ruins seem to have been blasted apart - strewn as in Puma Punku etc.. We are on the verge of a nuclear war once again (or so it seems possible). Makes me wonder (bring in Vimaanas?)
Based on the actual evidence, which is talked about in this and many other vids, it is clear to me that the old story we grew up with will not hold up in the long term. Those pyramids in China...I wonder how long before a mindset change results in removal of the trees planted etc.? What will be found underneath the dirt?? we'll likely never get the truth if institutions like the Smithsonian are involved.
Skeptics should challenge themselves to watch entire video's like the one above before throwing out statements time and again that we present no evidence. That's all we do...show them why their beliefs are not based in reality.
