Cultures of Europe, North Africa, and the East were very well connected during the times of the Silk Road and it's architectural styles and techniques naturally spread and occasionally appeared in places far removed from their origin.
As for cutting into rock, people are just good at that.
Look at the size of the doors.
Why cant humans replicate these into cliff faces today?
What makes you say we can't replicate those into cliff faces today?
Show me we can without some high tech lasers.
Ok, power tools cut through mountains like butter so that a single man can do stuff like this today.

So it's possible. But who's paying for large temples to be cut out from mountain faces in today's day and age? We're achieving engineering feats that would make ancient people think that WE'RE the aliens. And there are people who think it's the other way around? We are where we are today because ancient people mastered the art of stonework back then. Forgetting or ignoring that and attributing it to aliens is disrespectful to our history.
This dude is using tools that were supposedly not available thousands of years ago.
He’s not building into solid rock, it looks more like some kind of clay texture.
Your question was about being able to replicate the feats of our ancestors today, and I'm saying that you can. If you want better proof, take up the art and carve a baller temple into a mountain yourself.
