Final answer:
The worship of a sun god serves as the best evidence for the Moche culture's influence on the Inca empire. The Moche contributed to the spiritual and religious landscape of the Andes, which the Incas later adopted, particularly in the worship of the sun god Inti.
Step-by-step explanation:
The best evidence that supports the influence of the Moche culture on the Inca empire is D. the worship of a sun god. The Moche culture thrived in Peru long before the Incas and are known through archaeology and art for their contributions to successive cultures. Although the Incas had many aspects unique to their civilization, such as an extensive road network that rivalled the Romans and a complex imperial administration, the spiritual and religious influence they inherited from previous Andean cultures was significant.
The Incas worshiped huacas as unusual rock formations or peculiar features of the landscape, along with a pantheon of deities including the creator god Wiraqocha, the thunder god Illapa, and the sun god Inti. Inti was of critical importance as Inca rulers claimed direct descent from him, and this religious influence is something that can be traced back to previous cultures, such as the Moche, highlighting the continuity in religious practices.
The Incas encouraged the worship of Inti and built many temples in his honor, which helped to cement the relationship between the rulers and the peoples of their empire, a strategy that has roots in the religious traditions of cultures like the Moche.
