my 1st blog

Hey y'all this is my first blog... has anyone ever wondered about advances in technology? Well, I have and I was thinking that, if we are coming out with all of these "breakthroughs" how come people in earlier times didn't come up with them? like the egyptians? to me we have had the same resources as they did so why did we come up with these breakthroughs and not them? was it because we are more intelligent? i don't think so. i believe that our society dwells on more material things and doesn't worry much on intelligence. IF the egyptians did come up with say the iPhone centuries ago where would we be today?
