"oops,,,sacrifing=sacrificing. Should have just said "uncivilized"!
How can you call them civilizations uncivilized?
They were civilized, I tell you. See sample below:
Túcume civilisation
Andes civilisation
Moche civilisation
Lambeyeque civilisation

Another measure of a civilization is seen in their art; If I can draw or sculp it, it's proof they were primitive!
