ARROW

You know Persian god Tir (see Persian Tir) as Hermes. Tir literally means arrow, which explains why Hermes had wings on his sandals but not on his back or arms as one might expect. This is how we know the Greeks borrowed the deity from Persians and not the other way around. Tir used to be pronounced as tigr which is likely origin of Tigris (river), Tehran (capital of Iran) and Tigran (legendary Armenian king). Chief Persian god was called Ormazd (also Horomazes) and now you know where greeks got the name Hermes from.

Germanic god Tyr is symbolized by tiwaz rune ᛏ which is a coincidence.

In the tale of Trojan War Greek hero Achilles dies when arrow shot by Paris and guided by Apollo punctures his heel. In Indian myth a hunter named Jara shoots an arrow towards Krishna's foot that fatally injures him. I think both of these refer to the idea expressed by above mentioned arrow god Tir, since not only it's an arrow that kills but also the location of the wound matches that of Hermes wings. India and Greece are located on opposite sides of Persian Empire, another hint to where they got their stories from.

Have you noticed a little peacock at the bottom right corner next to Krishna? It's not accidental: Krishna is often depicted wearing a peacock-feather wreath or crown. Remember that many early Christian paintings and mosaics show the peacock. Christ and Krishna name similarity is, of course, accidental. As is tiwaz rune name similarity to Persian word for peacock tawus (طاووس).

Official etymology tries not to see the obvious: stems from Proto-Indo-European *deywós, meaning 'celestial, heavenly one', hence a 'god' (cf. Sanskrit: devá 'heavenly, divine', Old Lithuanian: deivas, Latin: deus 'a god, deity'), ... Sanskrit: Dyáuṣ, Ancient Greek: Zeus .... Deus and Zeus from Persian firebird peacock is just too much for modern science.
