How does one explain Hermes=Mercury?

I see H[k]=M, and m=c [k], that is k=, twice.

And the root Her- has the root for fire/heat that shows up
in various forms across various language families e.g. even Turkic
kIz (to heat up, get angry) < *kIr, Chuvash xer.

Furthermore, Turkic for sun is kUn < *kUyUn, and kuyash, which
should be the kentum (centum) IE word. But Turkic also has dozens of
these words, including the verb-root kUy, and kUw (to burn). We know that
verbs rarely get borrowed and that nobody has yet found a single verb in
Turkic that was borrowed from any language.
So is this (kUn) a borrowing from an unknown IE language or is
Turkic "the unknown IE language" descendant?
