Interesting Points to Chat About

I loved the movie and I am so intrigued about these questions! I have yet to see someone talk about the ruins and the chambers where the first cylinders were found with the decapitated engineer. The head looks to be an engineer, then there is a an alter of some sort with a green gem and artwork that looks to be Xeno from the other alien movies....SUP WITH THIS?!? :) When prometheus lands on the planet you can see there more then a few pyramids.....are they ALL identical or did they just happen to stumble upon the weapons factory. I also want to know if these engineers are so strong and resilient, what the heck are they running from in tunnels during the projection? Infected engineers? Xenos? How funny too was it when theses weapon making, galaxy traveling, "engineers" use a flute to turn the galactic star cruiser on and the buttons looked like pudding with LEDs in them....hahah still an amazing movie!
