Art say: Dark ages , or very early middle ages. We let the church keep the records and they were somewhat bias.

Tom say: It was destroyed in wars, natural disasters, etc,--along with the records. --not to mention simply rotting away between civilizations Not much man made lasts 10,000 or more years. Since we have been here 50,000 to 250,000 years, there has been PLENTY of time for civilizations as advanced as our own (or more) to have developed, get wiped out, and come back Thousands of years later, many times over.
We only know any kind of history no more than 10,000 ago.

oil field trash say: How do we know it is lost if we don't know what it is?

JosephV say: As simple as that. @Nyx: Because of all the new stuff that came along, and replaced it.
Man found the wheel, made of wood and stone, and put it to use at the time of Adam. The wheel today is much advanced with metals, motor, and electronics within it. The new stuff replaces the old, but the principle of the wheel still rolls on, calling us ahead.

Daphne say: They took it to the grave so that no one would steal their inventions. The way it was back then is not like now where people all over the world connect through the Internet and other ways. They needed to keep their discoveries to themselves to better protect themselves.
I heard the Great pyramid's in Geza created electricity.

Sciencenut say: Everything they knew back then has been rediscovered. We don't lack any of their technology today. Concrete was reinvented/rediscovered by a British guy a couple of hundred years ago. Even the Antikytheran mechanism has been shown to be an eclipse predicting machine.
