Buddhism is a religion that does not include the belief in a creator deity, or any eternal divine personal being. Buddhist teachings state that there are divine beings called devas (sometimes translated as 'gods') and other Buddhist deities, heavens, and rebirths in its doctrine of saṃsāra, or cyclical rebirth. Buddhism teaches that none of these gods is a creator or an eternal being, though they can live very long lives. In Buddhism, the devas are also trapped in the cycle of rebirth and are not necessarily virtuous. Thus, while Buddhism includes multiple gods, its main focus is not on them. Peter Harvey calls this "trans-polytheism". Buddhist texts also posit that mundane deities, such as Mahabrahma, are misconstrued to be creators. Buddhist ontology follows the doctrine of dependent origination, whereby all phenomena arise in dependence on other phenomena, hence no primal unmoved mover could be acknowledged or discerned. Gautama Buddha, in the early Buddhist texts, is also shown as stating that he saw no single beginning to the universe. During the medieval period, Buddhist philosophers like Vasubandhu developed extensive refutations of creationism and Hindu theism. Because of this, some modern scholars, such as Matthew Kapstein, have described this later stage of Buddhism as anti-theistic. In spite of the mainstream non-theistic tradition in Buddhism however, some writers, such as B. Alan Wallace, have noted that certain doctrines in Vajrayana Buddhism can be seen as similar to some theistic doctrines of creation. Early Buddhist texts Damien Keown notes that in the Saṃyutta Nikāya, the Buddha sees the cycle of rebirths as stretching back "many hundreds of thousands of eons without discernible beginning." Saṃyutta Nikāya 15:1 and 15:2 states: "this samsara is without discoverable beginning. A first point is not discerned of beings roaming and wandering on hindered by ignorance and fettered by craving." According to Buddhologist Richard Hayes, the early Buddhist Nikaya literature treats the question of the existence of a creator god "primarily from either an epistemological point of view or a moral point of view". In these texts, the Buddha is portrayed not as a creator-denying atheist who claims to be able to prove such a god's nonexistence, but rather his focus is other teachers' claims that their teachings lead to the highest good. According to Hayes, in the Tevijja Sutta (DN 13), there is an account of a dispute between two brahmins about how best to reach union with Brahma
