Let's talk about the assumptions and faith that are inherent in the statement above.
Your assumption is that serpents do not speak human language and that only faith in superstition would make someone believe otherwise.
Have you spent much time with serpents? I personally must say that I have not done so. I know next to nothing about what a serpent is capable of. Furthermore, the exact species of the serpent is not mentioned anywhere. Do you think that your experiences (whatever they may be) with serpents are indicative of all serpents everywhere in general?
How do you know that the serpents you have had contact with are a random sample of all serpents everywhere past, present, and future?
Oh yeah, serpents can talk?
But in human languages, no...unless, you are four-year-old, watching some cartoons on tv, where all sorts of animals can talk, or your mum reading fairytale or children's fables. Or perhaps, you think humans can talk in the languages of animals, like Doctor Dolittle or Harry Potter.
None of these are real. If you think it is possible, then please show us some evidences.
You can train animals do certain things, with commands, as you would do with pet dogs, only because you getting to respond to do things, but a dog wouldn't talk to you with human voice and speak in human language.
And there are birds, few of them, like cockatiels, parrots, that mimicking spoken human languages, but they don't understand what humans are saying; they don't understand the words they have mimicked.
The story in Genesis about Eden, were never meant to be taken literally. Many Christians and Jews still believe in God, but many of them understand the Eden episode is an allegory or myth.
The most important values is understanding the meaning in the messages that the allegory or myth are trying to convey, very much like Jesus' many parables.
The mistake modern Christians make, especially these creationists, is treating the allegory literally, as if it is history or science.
Hey, even I used to believe in the stories of the bible. I nearly join two different churches when I was still a teenager, one of them being my sister's church (15 or 16). The other church I nearly joined, was a pastor I had befriended and who attended the same college I did, but didn't join after a quarrel (I was 19 at this time). And I didn't stop believing in my early 20s, but being busy with my studies and later with works, my reading and attendance at the church trickled until I have stopped altogether, not because I became an "atheist". I was simple too busy with my life, that the bible, the church and the very idea of saving my soul were no longer my priorities.
But getting back to my point about allegory, I was treating the bible as if they were history, if not as science when I was a teenager.
So for nearly 15 years, I didn't touch the bible. When I began changing my career direction, I was doing my final year (in 1999), part-time, in computer science, when I decided to create a website for myself, just for fun. Originally, I was going to create webpages as fan site for two favourite fantasy novelists at that time - David Eddings and Raymond Feist. Instead, I scraped it, and decided to do website on Greek mythology, called
Timeless Myths.
I kept adding new webpages on Greek myths that year, and before the mid-year, I wanted to add Norse myths, to my growing website. Before the end of 1999, I decided to add Celtic myths. At the beginning of 2000, I wanted to add a new section about the legends of King Arthur and his knights, so on the day of Timeless Myths' one-year anniversary, I posted the
Arthurian Legends.
It is during my research on the legend of the Holy Grail, looking up, Joseph of Arimathea.
In Perceval (or Conte de Graal "story of the Grail", c 1185), Chretien de Troyes didn't mentioned Joseph as the original keeper of the Grail, which Chretien described the Grail as a platter, not a chalice. It was another French poet, Robert de Boron, who wrote a trilogy (c 1200), mentioning Joseph of Arimathea and describing the Grail as a chalice or cup that he used to catch the blood of Christ.
Hence, it renewed my interests in the bible, and in the months to come, I have began re-reading the bible from cover-to-cover. But my views have changed. I began to have doubts about the stories in the bible. I had also began looking up that were related to the bible, for instance,
Pseudepigrapha (e.g. The Book of Jubilees, the 2 books of Enoch), the legends and folktales of the rabbis in the Aggadah, and the infamous heretic literature of Gnosticism (the codices of Nag Hammadi, discovered in the 1940s, just like the Dead Sea Scrolls from the Qumran).
My other website -
Dark Mirrors of Heaven (2006) showed my interests in those non-canonical biblical literature.
I have read a number of other translations, from Egypt, from Sumer and Babylonia, from the old Hittite empire, and from the Ugarit. I had originally thought of starting yet another, website on all these myths, and I still have my notes of my research, but my life was too hectic from 2007 and onward, because my parents became ill for a long time.
My point in all this regaling of my time, is that my worldview have changed since picking up the bible again. With the 15-year hiatus, have stripped away all the church teachings and interpretations of the bible, and I was looking at the bible for the first time, with fresh eyes and new understanding, that many of these stories are just stories, or allegories.
And I have read enough myths to recognise that animals don't talk the human languages.
In the Old Babylonian epic - Epic of Etana, there is the story of eagle and snake, befriending each other, until the eagle betrayed the snake, by eating the snake's offspring. The snake took its revenge by crippling the eagle. The young king - Etana found and save the eagle. Etana and eagle can talk to each other, and in return for saving the bird, the eagle flew to the heaven, which a goddess gave Etana, so that he and his queen could have a baby.
This is just one of many tales, which human and animals can converse with each other. How is the story of Eden true, and not others?
You have admitted that you know not of any serpent speak in human language, that should be indicative of that's not possible, but you want to keep an open mind. But at what point, do you realise that it is merely a fantasy?
I still love reading myths. I even love reading Genesis creation and flood, and they are still my favourite parts in the bible.. The only differences between now and when I was teenager, is that the world made me see what I see, and I come upon the realisation that not everything that I read, are real...not unless I am tripping on magic mushrooms or acid.
