Buddhism doesn't have a god in the traditional theistic sense like many other religions. The central figure is
Siddhartha Gautama, the Buddha, who was a human being who achieved enlightenment.
While there are many figures in Buddhist cosmology, like deities and bodhisattvas, they are not considered creators or supreme beings to be worshipped in the same way a god is in monotheistic religions. They are often seen as beings who can offer guidance or help along the path to enlightenment.
So, the most accurate answer is: Buddhism doesn't have a single "god." The Buddha is a revered teacher and example, but not a god.
