Keep in mind and realize that we have gone from using horse drawn carriages and wagons in 1900 to the first nuclear powered aircraft carrier in 1961...in just 60 years...

Than how come we dont find plastics and other un-compostable materials in the ground? Plastic takes forever to decay, as the only way that it can break down is for it to die out because of halflifes of atoms.

Maybe they were so advanced that they created every infrastructure to be 100% biodegradable?
Nothing we have made,except glass,will last for very long and this link is a real eye and mind opener...Life span of common items > www.dot.state.pa.us...

If "those" forgotten and erased civilizations who rose and fell long before us even made glass,99.9% of it probably has by now been buried and crushed by tidal waves, volcanic eruptions, earthquakes, asteroid strikes, continental drift, superstorms, ice ages ect,ect, and maybe "they" were not a paper,metal plastic based society like we are...

So where are all the deposits of ancient glass from the time period of ancient advanced technology?
