In the Beginning, there was Nothing, which exploded.
Are you joking?
If you're not, then...
There is no "nothing".
There was something, just that we don't know what that something was before the Big Bang. It just that before the Big Bang, matters as we know them (atoms, including electrons, protons, neutrons), molecules, etc) haven't formed yet.
The current hypothesis is that the entire universe was nothing more than a singularity, in which it was very hot, and very dense, that matters/atoms can't form; the law of physics can't apply in pre-Bang.
And there is no explosion. The Big Bang just inaccurate name for the universe initial expansion. Space expanded. As the universe expand, so does space. And the more it expanded, the universe became cool enough for subatomic particles to form, atomic particles, like protons and neutrons, and bond to form atomic nuclei. Electrons formed later still, before they bonded with atomic nuclei, to form the first elements - hydrogen.
With enough hydrogen formed and coalescing together by gravitational force, eventually the first stars were formed. Other matters or elements were formed by these stars, especially when they died, either as red giants spewing stellar-materials out in space, or as supernova.
Our planet and the Sun was possibly formed out of the materials from these supernova.
This description is the simple or abbreviated version to the Big Bang. It is a lot more complicated (and longer) than this post.
