Practically all major religious traditions have incorporated Some form of Sun Worship- there are even traces of it in Christianity and Judaism. ( for example the hymn Holy, Holy, Holy, which puns in a sense Son and Sun- actually it states our SONG shall rise to thee. ( Mercedes-Benz version is Garage doors rise for thee!) the only exception- was the Norse pantheon or Aesir- there was no Sun God or even spirit in the Nordic mythology- which somewhat shocked Mythologist Edith Hamilton. It has been argued- by Ripley- that Baseball may have evolved from American Indian (Sun Dance).
