[quote] According to the Big Bang theory, the universe was born about 13.8 billion years ago. All the matter that exists today was once squished into an infinitely dense, infinitely tiny, ultra-hot point called a singularity. This tiny fireball then exploded and gave rise to the early universe. The singularity comes out of the math ofEinstein's theory of general relativity, which describes how mass warps space-time, and another equation (called Raychaudhuri's equation) that predicts whether the trajectory of something will converge or diverge over time. Going backward in time, according to these equations, all matter in the universe was once in a single point — the Big Bang singularity. But that's not quite true. In Einstein's formulation, the laws of physics actually break before the singularity is reached. But scientists extrapolate backward as if the physics equations still hold, said Robert Brandenberger, a theoretical cosmologist at McGill University in Montreal, who was not involved in the study.[/quote] its mentioned in the article.

I get that, but how did the matter in the singularity appear at all?

They don't. Nobody knows or has claimed to yet know where the singularity originated from outside of speculation.

Ok. That's the part I wasn't sure about. That's pretty much the reason I'm agnostic and not atheist...
