Those geoglyphs are incredible! It's so interesting how they are believed to be done for sacred purpose since they"... show their concern for death and in that way the lines could have been an offering to the Gods and a way to achieve immortality" The fact that they stand strong really proved the Nasca successful. In your research, did you find any Nasca-deniers out there who firmly believe and write of these pictures having been created by aliens or other beings?
