Final answer:
The continuity in religious symbols and motifs found in artifacts from the Indus Valley civilization, such as figurines and seals resembling later Hindu deities, suggests that aspects of the Indus Valley religion may have survived in subsequent Indian religious traditions.
Step-by-step explanation:
What suggests that the religion of the Indus Valley civilization may have survived for many centuries in a different form is the continuity in religious symbols and motifs. Artifacts such as clay figurines and seals have been discovered that bear a close resemblance to deities in later Indian religious traditions, such as the Hindu goddess Durga and the god Shiva. The presence of lingams and yonis, symbolic representations of male and female generative organs, point to a form of worship connected to Shiva. The custom of burying the dead with grave goods hints at a belief in an afterlife, a concept that persisted into later Indian religions. Additionally, the cities' advanced urban planning and the use of fire and incense in altars are aspects that could have influenced later religious practices.
