Sorry bro, not aliens but "ancient humans", ie: fucking aliens. Lets ignore the fact that you literally have pictures of the guy using block and tackle to move stones and we know of other techniques to do so.
The point is Astro, you can't differentiate someone who actually knows what they are talking about from people who spew bullshit. In fact, you start by assuming that if someone knows stuff, they apparantly are a "knowitall". Stop shitting up this thread with your idiocy and take the time to actually educate yourself on at least ONE TOPIC that you care about.
