Maria's Theory

I have been studying the lines and animals in the desert for a LONG TIME now, and I think that I have found a conclusion. The lines were there in order to show when ceremonies where meant to take place - when the sun lined up with one of the lines, a sacrifice was meant to take place. The animals were there to show which god they were worshiping - if there was a line going through an animal, then they were giving a sacrifice to that god. If there was an animal without a line through it, then they would worship that god, but not make a sacrifice.
