Babel as Man-Made Garden

The second chapter of Bereshit provides us with seven verses on the architecture of the Garden of Eden:

ח וַיִּטַּ֞ע יְהוָ֧ה אֱלֹהִ֛ים גַּן־בְּעֵ֖דֶן מִקֶּ֑דֶם וַיָּ֣שֶׂם שָׁ֔ם אֶת־הָֽאָדָ֖ם אֲשֶׁ֥ר יָצָֽר׃ ט וַיַּצְמַ֞ח יְהוָ֤ה אֱלֹהִים֙ מִן־הָ֣אֲדָמָ֔ה כָּל־עֵ֛ץ נֶחְמָ֥ד לְמַרְאֶ֖ה וְט֣וֹב לְמַֽאֲכָ֑ל וְעֵ֤ץ הַֽחַיִּים֙ בְּת֣וֹךְ הַגָּ֔ן וְעֵ֕ץ הַדַּ֖עַת ט֥וֹב וָרָֽע׃ י וְנָהָר֙ יֹצֵ֣א מֵעֵ֔דֶן לְהַשְׁק֖וֹת אֶת־הַגָּ֑ן וּמִשָּׁם֙ יִפָּרֵ֔ד וְהָיָ֖ה לְאַרְבָּעָ֥ה רָאשִֽׁים׃ יא שֵׁ֥ם הָֽאֶחָ֖ד פִּישׁ֑וֹן ה֣וּא הַסֹּבֵ֗ב אֵ֚ת כָּל־אֶ֣רֶץ הַֽחֲוִילָ֔ה אֲשֶׁר־שָׁ֖ם הַזָּהָֽב׃ יב וּֽזְהַ֛ב הָאָ֥רֶץ הַהִ֖וא ט֑וֹב שָׁ֥ם הַבְּדֹ֖לַח וְאֶ֥בֶן הַשֹּֽׁהַם׃ יג וְשֵֽׁם־הַנָּהָ֥ר הַשֵּׁנִ֖י גִּיח֑וֹן ה֣וּא הַסּוֹבֵ֔ב אֵ֖ת כָּל־אֶ֥רֶץ כּֽוּשׁ׃ יד וְשֵׁ֨ם הַנָּהָ֤ר הַשְּׁלִישִׁי֙ חִדֶּ֔קֶל ה֥וּא הַֽהֹלֵ֖ךְ קִדְמַ֣ת אַשּׁ֑וּר וְהַנָּהָ֥ר הָֽרְבִיעִ֖י ה֥וּא פְרָֽת׃

 Salient features of the garden:

1. A garden with all types of tree
2. Two mystic trees at the center- one of Knowledge, the other of Life
3. Gold and precious stones 
4. A river extending from Eden which branches into four rivers:
1. Pishon- not clear it's location. Opinions range from the Nile in Egypt to the Ganges in Ethiopia
2. Gichon- not clear it's location. Opinions range from Ethiopia to Mesopotamia
3. Chidekel- commonly identified with the Tigris in Mesopotamia
4. Prat- commonly identified with the Euphrates in Mesopotamia

Now compare this with the architecture of the city of Babel in chapter 11:

ג וַיֹּֽאמְר֞וּ אִ֣ישׁ אֶל־רֵעֵ֗הוּ הָ֚בָה נִלְבְּנָ֣ה לְבֵנִ֔ים וְנִשְׂרְפָ֖ה לִשְׂרֵפָ֑ה וַתְּהִ֨י לָהֶ֤ם הַלְּבֵנָה֙ לְאָ֔בֶן וְהַ֣חֵמָ֔ר הָיָ֥ה לָהֶ֖ם לַחֹֽמֶר׃ ד וַיֹּֽאמְר֞וּ הָ֣בָה ׀ נִבְנֶה־לָּ֣נוּ עִ֗יר וּמִגְדָּל֙ וְרֹאשׁ֣וֹ בַשָּׁמַ֔יִם וְנַֽעֲשֶׂה־לָּ֖נוּ שֵׁ֑ם פֶּן־נָפ֖וּץ עַל־פְּנֵ֥י כָל־הָאָֽרֶץ׃

Parallel features to Eden:

1. A city with buildings and eventually all types of language
2. A mystic Ziggurat-Temple at it's center(and historically two Ziggurats, one in Ur, the other in Babel)
3. City is made of bricks that form "stone"
4. The historic ziggurats of Ur and Babel are both in cities near the Euphrates river in Mesopotamia

So it seems like there are some strong parallels between these two passages in both text and subtext. What does this indicate?

I would argue that this parallel teaches us the nature of Mankind's sin in the Tower of Babel story. In the construction of this city & tower, Mankind was trying to build an artificial Garden of Eden. In this sense they were rebelling against God's decision to evict Man from the garden and exile them to our world with it's difficult day to day existence.
