»ZION .. the name .. and where its really exist«

yeah, it is deep.. i mean it maybe doesn't seem so if you were like driving between 2 points 4km apart.. but to think of 4km straight DOWN into the earth.. that is pretty deep.

Yeah...4000 meters is still only 2.4856 miles. That doesn't seem like it's enough to be near the earth's core.

I don't how to break it to you, but ... it's not Sinai, and it's not Israel either. I watched the Renaissance again and saw that 01 is situated in the Arabian Peninsula desert, somewhat between Riyadh (Saudi Arabia) and Kuwait. So I guess that the humans figured that the desert was good enough for the machines!

There is also a very strong symbolic scene not long after the above scene, where a fly is flying onto the UN-emblem (which resembles a map) which a cleaner is wiping. He gets annoyed of the fly and smashes it on the UN-map-emblem right in the vicinity of where 01 is situated. ... Well the vicinity would have to be pretty large, because actually the fly is smashed a bit south of Baghdad, at Karbala to be precise.
