Wang Chang was wrong about other things though. He rejected the idea of a spherical.sun and moon, and spparently of the idea that the moon blocked the sun during an eclipse, which were the tight explanations. While ahead in many areas, he was actually behind in a few other areas.Wang Chong claims that humans are products of nature rather than any deities; "天地合氣，人偶自生” (humans are born of nature) is his own words.
Buddhism isn't interested in origin at all; Buddha called it "the unknowable" or non-issue.
Wang Chong was way ahead of his time in many ways that many consider him a "time traveler" (穿越者）; he was never a mainstream thinker during his time.
