Is it a coincidence that the first two humans in the Bible is called Adam and Eve and the first two humans in norse mythology is called Ask and Embla?

Keep in mind that we're not 100% certain about the accuracy of Snorraedda as a mythological source, considering the heavily euhemerized and Christianized Prologus, and the very clear Christian parallels in Vǫluspá, from where the story of Askr and Embla comes.

While it's very likely that Vǫluspá is pre-Christian in its authorship (Bellows' 10^th century dating is probably not far off) there is a lot of syncretism that occurs in the poems and prose around it in the Edda. Terry Gunnel disputes the whole theory of Vǫluspá and the Edda in general as being representative of Norse paganism as a whole, and rather suggests that it is representative of Icelandic interpretations of pagan stories (which were syncretized with Christian teachings during the conversion)
