They built a pyramid, we havn't.
How can we tell them how to build it better, when we cant even achieve what they did 4000+ years ago? lol
But my point is it may be the only thing preventing us from achieving the same is an unwillingness to be blatantly immoral (not to mention finding a compelling reason to build one in the first place). If that's the case then, yeah, we might very well have grounds for telling the a better way to do the same thing. You never know. *shrug*
