What is so exasperating is so many people here saying this couldn’t be done, or that is impossible, or we can’t even do that today—yet there it is!
It WAS done.
I don’t think any of us can definitively say ONLY a modern computer-driven laser could have cut that stone. That is an assumption on someone’s part.
There in fact may be many primitive methods to do what is seen here we don’t know about.
How else can you explain them?
I don't think anyone here said that, not at all. I didn't. You're misconstruing comments. Maybe there are many hi-tech methods that were used that we don't understand. Maybe high-pressure water jets (which I've used to cut metal sheets for fabricating electronics equipment).

I had to laugh at how deftly Christopher Dunn got around a question/statement by Giorgio Tsoukalos. They were looking at some ancient artifact that looked machined and Tsoukalos tried to get Dunn to agree that it was made by aliens. Dunn replied that "It looks to be fashioned by machinery we have not yet discovered". That's what I believe.
We are told that homo sapiens has been on earth for at least 200,000 years, and that they had the same brain as we do today. That leads me to believe that higher civilization have existed and were wiped out in cosmic disasters. If 95% of humanity was killed today, how long would it take the survivors to come back to our present stage?
