And It All Started With a Big Bang... BANG!

Well, not certainly. Some scientists would argue this misconception that The Big Bang actually had a big bang. The leading theory is that it was not an explosion, but a very quick expansion. Space and Time are the fabrics of the universe and did not occur in any one place or at any one time, but it happened everywhere all at once. Think of the universe as a big balloon being inflated. Consider the Earth, our galaxy, and the billions of other stars and galaxies to be on the skin of the balloon. If you choose a point on the surface, you'll notice the rest of the rubber stretches further away with every inflating breath.

CMB

 With advanced technology, we have been able to pinpoint--what we think--is an exact period of time and direction in which the creation and formation of our universe took place. This time period is believed to be in between 1.0x10^-43 of a second and 1.0x10^-36 of a second.  Astronomers can measure this time frame through the bread crumbs left behind by the expansion. Namely, the Cosmic Microwave Background (CMB) which is leftover thermal radiation. This radiation is observed in every direction we look as long as we have the right equipment. So where did all of this energy and material come from in such a rapid amount of time? Though we can't be sure, many turn to multiverse theories for answers.
