Know the difference between the Poetic Edda and Snorri Sturluson's Prose Edda. The former is our primary source of information about the Norse gods and their mythology, the later is a secondary work of scholarship on the old heathen poems, written from and advocating the Roman Catholic Worldview and World History. Tacitus tells us that such songs formed the only record of the past among the Germanic tribes. They were considered heathen history, which is most obvious in Voluspa which encompasses all of human history from Ragnarok and beyond. When writing the history of the northern peoples, Snorri used these old poems as his source, and was likely working from manuscripts we know circulated in his time. He interprets the old verses as if the gods really were just human beings living on earth. This warps the worldview and shatters the ancient historical epic spoken of in the oral poetry.
Therefore, using Snorri's Edda to explain the poems of the Poetic Edda (which were his own source) assumes Snorri was correct in his understanding of the gods as ancient men from the Classical world, living in the Classical City of Troy in Asia Minor, or its sister city, patterned after Troy, that Odin and his Asia-men rebuilt in Sweden, according to Snorri in his pseudo-history Ynglingasaga and the Prologue to the Prose Edda. Clearly, those ideas are not heathen in origin, yet naturally explain the many contradictions between Snorri's Edda and the authentic heathen poems collected in the Poetic Edda.
There is much more in those old poems than we have been lead to believe!
