text: One reason this Face wasn't made by aliens is the fact that the Face isn't even a Face. This Face is actually about the same thing as a mesa or a butte. It's not a Face built by aliens but actully a natural landform. The Face has most likely been there for years, just only looks like a face when it's shadow sets on it perfectly. It's just a natural landform that's change over time, creating the face everyone saw.
