The Aztecs believed that the Gods needed at least a sacrifice a day to make sure sun could rise each day. Obviously they were obsessed with religion. The Aztec priest, as an everyday job saw lots of hearts and blood. This is because the priest ripped the hearts out of the people they sacrificed. They had to go to ancient buildings up a lot of steps to be sacrificed and they thought it was an honour. They used obsidan knifes / sharp stones from volcanos to rip the heart out.
