>it would take a lost of time for one artist and we're talking about making a goddamn giant stone walls.
What if you had a team of 1000 people?

> ancient people could make a soft stone
Why does this stone seem to be identical to hard stones that you can find in nature?

By logic it's a stupid idea and waste of time and human resources. That why i used term 'artist', because sculpting isn't an easy skill to master, and we are talking about hundreds of square meters of hard surface to connect to each other. People don't know how hard and time consuming is to manufacture even a simple things with modern machines and we're talking about peoples thousent years ago. To this day, If something is not efficient enough to produce, it wouldn't be mass produce.

>Why does this stone seem to be identical to hard stones that you can find in nature?
Because those are the same stones.

No it isn't. If you're a king, you can command people to make cool buildings. But on a more practical level, these kinds of structures are earthquake resistant. So there is a very logical reason to do this.
Why on earth do you assume that people in the past didn't like beautiful and impressive buildings anyway?

>Because those are the same stones.
Pic related is limestone. Are you saying that this stone, which is deep underground, was placed there by the sky people?

In industrial planning you should know, that if you want to make a huge constructions you should have technology to create elements fast. For example statues in cathedrals, castles etc. was given to artists, but contructiuon elements was made industrial. Kings and Faraons knew it, because they don't live for 1000 years to saw how their temple was made

>Are you saying that this stone, which is deep underground, was placed there by the sky people?
Im saying that in most cases or even in all cases natives tells about ancient recipe that can 'melt' stones using some kind of plant. This recipe was given to them by 'teachers/gods from the sky'. 

And those caves could have a specific stone with appropriate chemical properties to use this plant. So those stone from underground could be mine and transport to the surface and then Treated with softening, or mabe even make a primitive concrete

Anon, most big cathedrals took decades if not centuries to construct. The original architects never lived long enough to see their designs completed.
