Ancient Technology/Civilizations

Introduction to my thoughts on Ancient Technology/Civilizations.

People are so used to believing that the current era that we are living in is the era of "cutting edge technology" and that such a benefit was not available to mankind before.

But is it true.....can we belive it to be true..when we look at monuments/technologies built by ancient civilizations such as Egyptians, Greeks, Chinese, Mayan, Indians etc..

Pyramid built thousands of years ago.....is still a puzzle for many scientists/archealogists - it looks like a tomb, it acts like an astronomical observatory, its perferct trianlge/tangent construction is a geometric wonder - what exactly is it ?

Decimal number system was known to Ancient Indians for thousands of years and infact it was the only civilization that utilised it. The concept/meaning of zero which is responsible for the digital technology today was defined ages ago in ancient India.

Mythological stories in ancient civilzations such as Egyptians, Greeks, Chinese, Mayan, Indians tell tales of Super humans and spectacular weapons and flying systems...are these merely myths or are they real.

Civilizations so powerful - where did they vanish - where they destroyed or did they leave our dying planet to other planets/galaxies.

Of the thousands of years of history of mankind..and its existence .....is it fair to belive that superior technology only happen to exist in the last 2000 years only ?
