I submit for your examination the Poetic, or Elder, Edda. In it, you will find mention of Atilla the Hun, who we know to have actually existed.
Furthermore, we have evidence of several other figures mentioned in the poems of the Elder Edda. Once a week, we have a tribute to Tyr, Odin, Thor, and Frey. They happen to be Tuesday, Wednesday, Thursday, and Friday. (We also have a day for Saturn, the Sun, and the Moon. Kinda strange that our week lacks a Yahwehday, and a Jesusday...)
Furthermore, the poems tell of places they we are able to locate on a map. The Elder Edda provides the same level of historical accuracy as the bible.
Wasn't that fun?
I bet we can do the same thing with the Koran, or the Greek/Roman myths, or the Celtic, or the Egyptian, and so on and so forth.
