That "something" might have been Nothing.
Attributing that event or non event to God or any God is just nonsensical and part of your upbringing only.
The "Magic Man done it" approach is not an answer, it's a cop out.
It has no basis in reality. Everything could just have been here all along....
The Big Bang and the instant inflation could be a cycle of events that we cannot understand via our short lifespans...
There are more interesting creation myths on the shelves anyways.. http://www.desy.de/gna/interpedia/greek_myth/creation.html
"In the beginning there was only chaos. Then out of the void appeared Erebus, the unknowable place where death dwells, and Night. All else was empty, silent, endless, darkness. Then somehow Love was born bringing a start of order. From Love came Light and Day. Once there was Light and Day, Gaea, the earth appeared."
The Greeks were awesome.
