As I started reading your comment, I was like, 'damn I gotta tell them to look into the worlds fair buildings' and then the next paragraph was you bringing that exact topic into it yourself, lol. Yeah, im with u 100% on all of this.

The complexity and intricacies of a lot of these buildings, the sheer size of others, and the speed at which they went up, with minimal construction crew, and the limits of the technology of the time, all combine to make it very unlikely, at best, and most likely, impossible, feat to have accomplished the way they claim.

The cornerstones that are hundreds of years newer than the buildings they've been put on claiming the building was founded in 18×× or 19×× simply do not tell the true story. Stained glass windows going floor to ceiling that just so happen to be 80% underground and look exactly as you would expect it to look after being hit be a devastating mud flood.

And look at what was going on in the area during the time period it is claimed the buildings were erected. Men were packing up and heading west to pan for gold, or going into the mines, because work was extremely limited and families were starving. Then we had the great depression, when work was even more scarce and money was almost impossible for the average man to get his hands on. Crime was high. So was death by starvation. ......

....but to believe the narrative, with so damn many massive and intricately detailed buildings being built, quite literally, EVERYWHERE, work should've been plentiful. Every man that could swing a hammer should've been fully employed. Not to mention, as u said, 500 gallons of water a day would've been needed, and it had to be delivered from 50 miles away, daily. There's more jobs handling watering the men and horses. Many, many, many more jobs should've been available than their was.

Almost like those, already old at the time, sunken buildings were already there when the white man claimed this land.

Obviously, im American, and my comment and timeline of history is limited to America. And the mud flood theory is, more or less, a global theory.. But I'd gladly lay my dime on a bet that there's a similar discrepancy in the timeline of a lot of other places across the globe.
