It may be true that our ancestors had much superior technology than us, but the question arise what happen to that technology? I don’t believe in the explanation of war or total disaster has occurred and we all went back to plain dum without anything from that technology. And other thing there are no evidences like how they have improved that technology and what are the stages and how they improved, how it came etc.. It just we all know they used some advance technology coz we see their creations.HishamZz said:
Lets take animals we can see bones of them in different stages of evolution. So we know they have improved and they have changed like that. Lets take iron we have evidences how iron used in ancient times and how improved, how it evolved etc..
But about these magical creations we only see those things has happen but no back tracing.. how it happened no evolve path just it has created some magical things we still can’t explain. About the Pyramid example one of the biggest mysteries is how they have moved those large stones? You can’t find that type of rocks in nearby area. They only exists far away places 100s of Kilometers away. They are so huge, today’s huge hydraulic cranes can only lift them. There are so many mysteries about how they created such mathematically accurate structures, 3 pyramids align which resides many kilometers away, large drawings in desert floor showing path to someone coming from space, drawings of unknown creatures and vehicles etc...
Hishamzz about the SETI, I got the mail from them telling about their financial problems etc... But they have started their project again.
Some say in Area51 or some secret project knows some stuff about aliens and they have contacts with them. But I don’t believe in that.
What I really believe..
“We are not Alone in this Universe”
oh yeah..forgot to mention the buried city ATLANTIS where the doors to our past still remains closed. 
hopefully it'll answer alota qs.
