How to make a flat surface on a soft stone: - chip away at it until it is approximately flat - rub it with something for a while - call aliens to show them your highly advanced new technology: a flat surface
About these "advanced ancient civilizations": 1) where did they come from, and where did they go? 2) where are the artifacts? 3) Where are the advanced tools? 4) specifically what technology or knowledge did they posses that was anachronistic? 5) Where are the materials describing these processes, technology, and knowledge? Are we to believe this information was all passed through the culture for thousands of years verbally? Where are the books? Guesses are fine.
I have yet to see for myself Mt. Everest. Suppose somebody told you they saw it and you told them what you said above? That senses can be tricked, photos faked, etc. You say to them since you never saw it yourself, it does not exist. I do not get the pure strict remarks that unless you saw it, it is a lie. Somebody asked Trump if he has looked into UFOS as president too. And he told them yes. And then he was asked if he wants to comment more and he says no, he does not. This I saw him say on TV. I hunted for the you tube but never found it. However he promised to make public what he learns about ufos. I hope he does.
And yet you can choose to go there and see it for yourself. Then, leave. Then go back again, and... oh, look at that, it's still there, right where every single person on the planet (not a smattering of people) has always said it has been. You can take a piece home with you. Sorry Robert, that is just not a good comparison.
So your guess is that those ancient advanced civilizations were influenced by aliens? I just said the civilizations were ancient and advanced. "Aliens" is a whole, other level. Aliens, eh? Okay.
A small band of Aliens could do wonders. They were looked at like the gods, and written about as the Gods. They had lots of laborers at their disposal. They also has no building materials, no infrastructure, just stone. But somehow they could cut, and move giant stones easily. something we cannot do today, in many cases.
Machu Picchu is granite. Granite is not soft for a man to carve. Granite rates 7 on the Mohs hardness scale and diamond is 10.
Oh, I long ago have my pet theory on the arrival of humans to Earth. Brought to the various continents by aliens it explains so much about the variety of humans. However, we would be like the aliens so perhaps aliens is not a good word.
I can't say how easy but they did cut extremely flat surfaces. I once owned a machine shop. I realize the task I speak of. 50 ton blocks of granite take a lot of work to make as they are on that mountain.
Here we have rock drilling, something done today, however. This cuts about 1/8 inch per revolution. Something we cannot do today.
I too, worked with machines all my life. I can look at any just about object, and tell you if it was hand, or machine made, and in most cases tell you what kind of machine was used.
Easily? Where did you come up with that? Building these things likely took many years or decades. We can build the same thing in weeks or months. It isn't. You need harder granite. Or bronze. Which they had both of. Again? Easy? Wha? By what measure? I'm sure a lifetime of chipping granite out of the quarry and carving it didn't seem to easy, to a slave.
You can see by the pression of the cuts,, no mistakes, lots of them not necessary for the project. cutting stone was relatively easy for them.
You can look at the cut marks, there are other pictures also. Even the excuse of brass and stone powder is no good, because it will not leave the same marks. To analyze and understand this, you have to have a basic knowledge of machinery
Oh yeah? Then what machine made those squiggly corners and edges all over the art pictured earlier from Puma Punku? They sure weren't very straight. And what machine carved all those uniquely shaped blocks of granite? It's as if they just kind of had to work with the shapes they were given, a lot of the time, isn't it? Why not, just all square blocks? Heck, why not lots of isosceles triangles, and dodecahedrons? Where are the tertrahedrons? T No you can't, most of the cuts and surfaces are hidden. And many we can see are actually rough, even to the untrained eye. And if this was all so "easy"..... why so few structures? Why no other advanced tech? Did the aliens fly here in a floating, stone castle? Come on.
Here are a few articles on the Inca that deal with Machu Picchu and other sites. This is real scholarship, not the fluff produced by Sitchin, von Daniken, etc. No “aliens” were required.

"For all I know we may be visited by a different extraterrestrial civilization every second Tuesday, but there's no support for this appealing idea. The extraordinary claims are not supported by extraordinary evidence." ~ Carl Sagan, Encyclopedia Galactica
To be sure. But we could be made of star stuff brought here long ago on asteroids which evolved to where we are today.
But, they’ve been watching us a thousand years ago. We certainly weren’t that interesting then. Heck, we generated radio signals only ‘ recently”. So we’re waiting for nearly another thousand years for an answer. By then, climate change could either have drowned us or forced us back into the sea...either way, we’re not that interesting.
If there's a guy in a ghillie suit with an M82 rifle watching somebody through the scope they'll never know it. Not before. Not after. It's kind of an alien thing.
Who? I gave my pet theory freely and with no malice. Sagan may not have accepted Mt. Everest either based on not seeing it himself. (however it is, if not that Mt. some other remote mountain. )
“The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust.” ― Neil deGrasse Tyson
