Which religion did mohenjo-daro and harappa show that the religion of the early cities was later obsorbed into

Some elements of Hinduism appear at Mohenjo-Daro and Harappa, shown in the sacred status of certain animals (especially cows) and certain trees (such as the pipal). The two cities seem to have had ritual bathing and yoga postures, sacred Hindu symbols (such as the swastika and the lingam), and some aspects of Hindu gods such as Siva and the Mother Goddess (Devi), so many scholars believe that at least some from of Hinduism already existed in these ancient cities.
