Don't Hindus worship various gods? So why can't Greeks? Just curious; no flames please.
Not just various, but the same, related Indo-European gods. In India, it never died away.
Zeus, poetically referred to by the vocative Zeu pater ("O, father Zeus"), is a continuation of *Dyaēus, the Proto-Indo-European god of the daytime sky, also called *Dyeus phaetēr ("Sky Father"). The god is known under this name in Sanskrit (cf. Dyaus/Dyaus Pita), Latin (cf. Jupiter, from Iuppiter, deriving from the PIE vocative dyeu-phetēr), deriving from the basic form *dyeu- ("to shine", and in its many derivatives, "sky, heaven, god"). And in Germanic and Norse mythology (cf. *Tīwaz > OHG Ziu, ON TÃ½r), together with Latin deus, dīvus and Dis(a variation of dīves), from the related noun *deiwos.
To the Greeks and Romans, the god of the sky was also the supreme god, whereas this function was filled out by Odin among the Germanic tribes. Accordingly, they did not identify Zeus/Jupiter with either Tyr or Odin, but with Thor (ÃÃ³rr). Zeus is the only deity in the Olympic pantheon whose name has such a transparent Indo-European etymology.
In addition to his Indo-European inheritance, the classical Zeus also derives certain iconographic traits from the cultures of the ancient Near East, such as the scepter. Zeus is envisaged by Greek artists especially in two poses: standing, striding forward a thunderbolt levelled in his raised right hand and seated in majesty.
Aside from forced transformation, Zeus is known to punish those who veered out of his pleasure with lightning bolts.
