The early Udayagiri Caves reports appealed to the prevailing conjecture about the rise and fall of Buddhism in the Indian subcontinent, the hypothesis that Buddhist art predated Hindu and Jaina arts, and that Hindus may have built their monuments by reusing Buddhist ones or on top of Buddhist ones. Cunningham presumed that the broken Lion Capital at the Udayagiri Caves may be an evidence for these, and he categorized Udayagiri as originally a Buddhist site converted into a Hindu and Jaina one by "Brahmanical prosecutors". However, nothing in or around the cave looked Buddhist, no Buddhist inscriptions or texts supported this, and it did not explain why these "Brahmanical prosecutors" did not demolish the nearby bigger Sanchi site. The working hypothesis then became that the Lion Capital platform stood on a Buddhist stupa, and that if excavations were done in and around the Udayagiri Caves hills then the evidence will emerge. Such an excavation was completed and reported by archaeologists Lake and Bhandarkar in early 1910s. No evidence was found. Bhandarkar, a strong proponent of the 'Buddhist converted to Hindu' site hypothesis, went further with excavations. He, state Dass and Willis, went so far as "to ransack the platform" at the Udayagiri Caves site, in an effort "to find the stupa he was certain lay below". However, after an exhaustive search, his team failed to find anything underneath the platform or nearby that was even vaguely Buddhist.
