i share your opinion. every era has it's unique advancements. I don't agree with people who say we are the most advanced era of the history of mankind. I believe some of our ancestors had knowledge and skills that we can only dream of having. You can never know of the ancient world completely - they could have technology and knowledge far greater than those of us.

and i wonder why getting a permit to investigate the pyramids of china has been denied in all cases, and why investigating them carries a death penalty........ i wonder what wonder could be hidden there that they want to hide so badly
