What existed before the Big Bang?

A little research has taught me that before the Big Bang, all the mass in the universe existed in a tiny singularity. Since time slows around large mass, and this had all the mass in the universe, time didn't exist before this. Technically this means there is no "before" the Big Bang, but I was wondering if there are any theories as to how that singularity came into existence out of nothingness?

based on what we know now of physics, "before" the big bang did not exist. It created matter, and without matter (e.g. at least whirring electrons) we don't have time because there is nothing to measure.
