There aren't two creation accounts in Genesis.

It is a matter of Halakhah that the universe was created ex nihilo 5776 years ago.
Qabbalah is not for amateurs. One doesn't even begin to study it till one is forty years old. And despite the misuse of Qabbalah by concordists, there are plenty of Chassidic mystics and Qabbalists who interpret the chronology of Genesis quite literally.
Something I always found curious is the Nordic Yggdrasil tree connected to nine worlds and the Kabbalistic Tree of Life connecting ten spheres ;)
