Actually we now know how the Egyptians moved the blocks; they simply used the water and mud from the Nile which allowed easy transportation. Also with the line-up with the stars, you should consider how religious these people were, what the stars meant to them and all that.

How you describe early humans as being able to communicate psychically "Like animals", you're not totally off the mark there. We humans have a special (and very common) organ in our nose, it's purpose was (past tense cause with the development of complex communication we no longer used this organ) to detect different chemical reactions caused by themselves or others. The application of this highly useful organic tool was in finding mates, detecting predators (picked up the adrenaline), and basic territorial signs. Sooo, yeah. Nice video though. And although this might not be your belief, you should check and double check multiple sources. :)
