I don't think it's the same type of tech but stuff like farming much earlier than traditionally thought etc. Not gonna drop some alien pyramid shit on you b/c I don't believe it. Slaves... lots of slaves in a highly ordered society. But I think it's perhaps older than egyptian scholars believe and the evidence of such got wiped out w/ time. i.e. no trace of tools found for stonecutting etc. rusted to nothing w/ the thousands of years during the iceage perhaps idk.
