Where was Adam in the garden when the snake tempted Eve (Chava)? Nowhere. Because the temptation of Eve never happened.[1]
Additionally, how could Chava be fooled or cheated by a snake when they can't actually speak? We know that animals do not speak because it is contrary to the nature of things. A breach in the laws of nature. The truth is: natural law is fixed and needs no change. To suggest otherwise is arrogance in claiming that they alone know better than the Creator. As empirical observations well tell you, animals simply do not possess highly evolved language skills nor the complexity of writing. How then, should we reinterpret the Bible, especially Genesis? It was a parable. Which is to say that animals do not have the same kind of vocal cords as humans. At best parrots can talk, but they only go by repetition and cannot produce sentence structures on their own. What then, is the metaphor?
The "Garden of Eden" story is about morality and intelligence, and the duty and obligation to develop one's intelligence. It is certainly a mitzvah, one in which the Torah expects us to observe. Verbal intelligence is the tzelem Elohim, “the image (or, form) of G-d,” often mistaken to be the soul, (or in Hebrew שפנ).
Genesis 2:7 reads:
“The L-rd G-d formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a nefesh chayah.”
Onkelos does not render this simply as “a living being,” but characterizes this as man's ruach m’mal’la, “one with the power of speech,” a phrase denoting a certain level of intelligence.
Since G-d does not emit evil it is inconceivable to image that G-d would produce or create "dark forces" such as Satan or malevolent talking serpents (snakes) to manipulate or distort the creation of the world in which the Bible calls "Very good." In fact, it would be an insult to G-d and His Torah, G-d forbid, if people were to read the text in a literal fashion, promoting secularist to mock religion. Indeed the Zohars call such a person a fool.
In a similar vein, the Mishnah Hagigah 2:1 states:
“Whoever has no regard for the honor (kevod) of his creator is worthy of not having come into the world.”
In his commentary to the Mishnah, Maimonides explains “the honor of his creator”:
“This means whoever has no regard for his intellect, for the intellect is the glory of G-d.”
Thus the lack of use of one's intelligence when decerning these matters would be anti-religious and certainly not pious. G-d desires that we use our intellection and our five senses when reading scripture. In short, to do otherwise would be akin to one who commits intellectual suicide since our intelligence is, in essence, the only thing that separates us from animals, "an image of G-d."
[1] It is worth mentioning here that Adam and Eve most certainly did exist but that they had a mother and a father like you and me.
