The Romans used the word Deus for god
the Greeks worshipped Zeus
the germans worshiped Tiwaz pronounced Tew-vas
the Baltic states Latvia, Estonia, Lithuania worshipped deivas all the gods have the same story, they are sky gods that married a god of nature/the earth and created all other gods
Zeus was the son of Kronos and Gaia, he would later kill his father and become the father of all gods, hanging his father's corpse in the air to create the sky
Tiwaz pronounced Tew-vas was in Germany worshipped in place of Odin
In the Germanic story of creation Odin, Wotan, Woden-naz kills the giant Ymir and from his body, he crafts the world and takes the mantle of the All-father of the gods.
The story of a giant being slaughtered and his body being made into the earth even exists in India through the Rigveda where the cosmic creature Purush sacrifices himself to create the world.
In Ireland, The Dagda, Dago-deiwos.
The Dagda was a god of wisdom that held a staff that could kill with a single strike he though not the father of all gods has a similar narrative to that of the others in that he is a wise god and a father of many other gods.
A map of Indo-European languages.
All European peoples came from southern Russia and through conquest spread as far India.
I believe that the reason all these stories share similar narratives is due to our ancestors all sharing the same gods, the same stories, the same blood.
When I read of the old gods, I think of when our fathers in ancient times stood in awe of power of the natural world, of the raging storms and the beauty of the unending blue sky.
The god of Europe is the god of wisdom, the god of the sky, and storms.
