I could potentially write an essay on why skills are lost over time. Let's take one simple example. All school children are taught the first electrical battery, known as the voltaic pile, was invented by Alessandro Volta in 1800.
However it seems the application of transferring electricity via a voltaic cell was understood 2000 years earlier.

So if the science of batteries was known and applied 2000 years ago in electroplating then why did we forget?
Answer: new empires come along, wipe out older ones killing everyone.
Heck! ever heard of the dark ages? Greek/Roman science was lost for 1000 years, infact Europe had to re-learn the basics of science from the Arabs.
Archaeologists seem to have a problem applying what happened in the modern era to loss of knowledge in ancient times. they have been allowed to be gatekeepers of inquiry and block legitimate investigation under the guise of labelling everything as pseudoscience. Gobleke tepe was a slap in the face in 1992 when archaeology made fun of Graham Hancock's proposal that advanced civilisations existed prior to 3000BC.
