Nope. The first article goes into depth as to not only why the universe has always existed, but why it's an impossibility for it to *not* have. The paragraph explaining this (which is really the most important paragraph in the article) is the one that starts with, "Because time and space are both dimensions, the most useful analogy regarding the origin of the timeline and the universe deals with the latitude of a sphere."
The first article, the one dealing specifically with the origin of the universe, is fairly short, and can be read in just a few minutes. The second article is a history of the universe from its origin all the way up to now, and might take a good fifteen or twenty minutes to get through. Considering the depth of the subject matter, though, all in all it's not terribly long, and I think you'll find it worth the time.
Addendum II: Dustin - "Just saw Alexis' answer...wanted to clear something up real quick, a singularity is a single point in space. It has no dimensions, no height, no width, anything. What it does have is infinite density. (good luck understanding that lol)"
Well, a singularity isn't a single point *in* space. A singularity *is* (was) space when it exists as a single point.
Also, it doesn't technically possess infinite density; rather, it possesses the universe's physical analogue for infinity, in the same way that the speed of light is the universe's physical analogue for infinite speed, and the Planck Temperature (about 10^32°F) is for infinite heat. Of primary importance is that multiplying the universe's physical analogue for infinity for a certain quality by zero yields a meaningful nonzero product (the zero mass of a photon multiplied by the "infinite" speed of light mathematically provides the particle a real, nonzero momentum, etc.).
