Shocking Images from Google Earth! (Video!)

I stumbled upon this pretty incredible video. The youtube poster states that it has not been modified. Pretty amazing landform and shapes. I wonder if they mean anything. What do you guys think?

Nice and... freaky.
The Davids' star and the Illuminatus signs were kind of strange. Th others, the cave painting style ones were really quite strange. The cave men had hot air balloons!

The Triangle with the circles in it is either a bombing range taget, or a satilite target.
The alien looking fellow is a Nazca line.
The rest are just natural formations.
