> Dyaus-pitar and Jupiter, Zeus-pater

This one is slightly more interesting than a mere cognate as it is believed that the Proto-Indo-European speakers worshipped a sky god with the reconstructed name *Dyḗus ph₂tḗr ("sky-father") which is the ancestor of these (also Tyr and the like on the Germanic side). See:

https://en.wikipedia.org/wiki/*Dy%C4%93us "*Dyēus is considered by scholars the most securely reconstructed deity of the Indo-European pantheon, as identical formulas referring to him can be found among the subsequent Indo-European languages and myths of the Vedic Indo-Aryans, Latins, Greeks, Phrygians, Messapians, Thracians, Illyrians, Albanians and Hittites."

What I find interesting is that the primary Turkic/Mongolic deity, Tengri, is also a sky father. There’s no shared genetic or linguistic ancestry there, just two different steppe nomad populations independently deifying the daylight sky the same way.

What you are talking abyis gök/kök tengri (lit. sky god). There are other gods in Turkic/Mongolic pantheon, like ülgen/ulgan, yer tengri (earth god).

There is a connection. Not DNA, but via trade with the Saka/Scythians, who where descendants of PIE speakers

All steppe nomads are culturally descendent from Yamna.
