People who shout about ancient aliens and hidden technology always completely ignore that the people in the past had access to the most advanced machinery available: humans.

Add time to that, so that your project can have a scope of generations, passing down knowledge gained from a lifetime of doing this particular thing, the results become unsurprising even.

Amazing, inspiring and ingenious but also unsurprising.

Yeah, human craftmanship can reach really, really complex heights.

I guess industrialization has made lot of people oblivious to this fact.
