Cool stuff.. Makes me miss having the Discovery/History channels

I love absorbing a good history documentary every now and then...

My favourites are definetely the ones regarding old civilizations... Insane stuff they built back then... I would love to be able to travel back to those days and discover how they built some of their structures, and what knowledge they had.. It's truely amazing and awe inspiring what was done by the supposably "primitive" people.... Some things border on unexplainable even by todays technologies... Some things they built, would today cost billions and billions of dollars and take 100's of years, and we would NEED some of our most advanced and gigantic machinery just to complete the task... They did it all by hand with supposably limited or no technology or knowledge..

Simply amazing...
