Heck, you can even imagine a huge (sub light) generation ship hidden beyond the Moon sending stealth scout craft or probes. But there are no reliable pieces of evidence to back this "less implausible" scenario also. So, its nothing, it has no value, its just another wild speculation, it is not a theory, it does not make UFOs as alien machines more likely. One needs reliable evidence to do so. Once the evidence is present, then the speculation may become a hypothesis and eventually a theory.
Got reliable evidence UFO buffs?
It's interesting that Disotell poses the same question that I have thought of over the years when it comes to this subject. Why didn't the aliens build, or assist in the building of sky scraper like structures. Certainly with their supposed tech they could have done that. Not only that, but why not use advanced materials like glass and steel and concrete for construction? I think the lack of such building practices proves that is was our ancestors that built these structures witout the need for alien help.
Yes of course, I almost forgot there were people who claim to know the mindset of the "aliens". Perhaps you could fill us in Yeah_Right?
I on the other hand contend that we cannot conclude anything about the "intention" or "motivation" of any supposed "aliens". There is simply no rational method that would allow us to conclude any such thing...
Therefore any questions on the theme of "Why didn't the aliens..." or "Why don't the aliens..." presupposes that someone out there knows the mind of the "aliens" sufficiently well to actually answer the question - which of course is pure woo!
Which means of course that anyone proposing to make a substantive point based on any supposed answer to the question is just propagating pure nonsense.

The technique the researchers found most productive in making straight, tight joints between stones was to dust the bottom stone with stone dust, and lower the top stone into place. Its weight would compress the stone dust and leave a clear impression of where stone needed to be removed. Impact spalling with a hard cobble would quickly break the stone away from the places it needed to be reduced in size. The most daunting task was the several times that the top stone had to be lowered into the course before it was sufficiently well fit to be left in place, but it was manageable using brute force, ropes, and levers.
Do you have any insights as to how they managed the corner cuts, and their right angles?
Every time I hear someone like KoTA talk about our ancestors being incapable of building certain ancient structures, or that ufos appear in ancient art etc, I always think that Erich Von Daniken was a great con artist in getting people to believe such nonsense. Now I am not sure that KoTA has ever read Daniken, but I have a suspicion that he has.
Chisels?
Chisels?
Try this oneShow me... Let's SEE "evidence" of 2200 year old chisels capable of cutting right angle corners into diorite.

Basically. Pointed rocks. They were either struck by a hammerstone like a chisel or used as a hammerstone themselves. An example is described on page 16 of this reference, and appears a page later as figure 24. It has wear both on its pointed end and its blunt end, so was presumably struck by another stone, which would technically make it a chisel.

This isn't the work by Jean Pierre Protzen I referenced earlier, as Scientific American Magazine doesn't have free archives, but one of his other works, as archived by JSTOR.org.
I'm going to keep emphasizing here that our ancestors were capable of far more than we give them credit for. The common picture of ignorant, ineffectual savages is just us stroking our own egos. The fewer tools you have to work with, the more intelligent you have to be in order to use them.

Good link...not great, but 'good'.
No evidence of the "saws" or "abrasion cuts" featured... It DOES feature results from facing/dressing experimental techniques that could have been employed to form 'squared blocks".
Cutting a square 'into' a stone, however, is a different task altogether.
Actual evidence of how these cuts were made is lacking.
You link doesn't explain Pumapunku.
Thank you though, I enjoyed the insights.

Really?
First off, they wouldn't have been 2200 years old at that time. They would have been just made.
Even if they weren't "officially" chisels, and were just pointed rocks like the Speaker (Andrew Wiggin, for you non-sci-fi people) says, it's no big revelation that rock can chisel rock.
And making right corners isn't some magic property that the chisel itself has to have. It's the sculptor, not the tool. The person USING the chisel has to know how to make right corners.
You understand what a right angle is, right?
You've seen the images of the stones in question, right?
The link above noted that the 'lines' cut into the stone weren't a result of smashing/pounding, but rather from "abrasion"...
So, where are these 'saws'?
OH MY GOD
Andrew can see the FUTURE!!!
