This is going to be my comeback the next time I get called a conspiracy theorist. Not that I am much of one or discuss them very often.
We definitely aren't told the whole story on 911. There's so many wierd pieces like the dancing Israelis, the Pentagon footage, the 'crash site' in the field seemingly void of most of the expected debris, and tower 5 collapsing after office equipment caught fire somehow. It's the only time in history that 3 buildings were hit by 2 planes and collapsed into their own footprint from fire damage. Tower 5 is the smoking gun, look into that one.
The JFK assassination. Wendigoon did an excellent video (he's quite passionate about it, he has a full on whiteboard to go through all the facts). There's definitely more to that than we know. Crucial evidence being 'lost', audio of the gunshots, direction of the bullets... the person signalling with the umbrella on a sunny day..
Just to mix things up a bit, water erosion around the sphinx. You can clearly see in old photos the water erosion from flooding. The last time that area was flooded was thousands of years before the supposed age of the sphinx. There's also the tiny head and massive body, indicating that the head was recarved at some point. Then there's the complete lack of hieroglyphics inside the pyramids, while everywhere else, temples, tombs, etc have hieroglyphs everywhere. Perfectly circular drilled holes in granite, scoop marks in the granite around a half carved obelisk, and the sheer weight of the obelisks themselves. I'm not saying aliens but definitely technology existed back then that we are unaware of. Probably not like modern technology but very advanced and clever cranes etc.
Theres this guy on TikTok demonstrating exactly how you can move large and heavy objects like that with nothing but clever counter balancing and some well placed logs. It's really not that hard. Honestly this all was debunked ages ago, and just the fact that you willfully ignore that makes me think you're disingenuous about the other stuff you're saying.
I would argue that we know it could have been done that way. And that's ignoring the scoop marks in the granite, the drilled holes, lack of hieroglyphics. And apart from that, ignoring the main point which is the evidence pointing to an even earlier civilisation that created the pyramids/sphinx
To address the flooding but, I've heard the idea (nope, I don't have a source) that some of the ancient structures along the Nile may have been built with the assistance of dug canals that would have allowed barges to move right up to the job site. That could have been. Why the sphinx had wet feet, it was built in a puddle.
