Why are we here?

Ok, so usually people think of "nothing" as completely empty, like the number 0, but you can also imagine the number 0 as being completely full of every possible value, both positive and negative. Apparently, the structure of mathematics are such that they live and die by natural selection, alternating between states, and one state has the possibility of resulting in a "unit of space" being created. You could call this the "planck length", or smallest possible area. It has the values of -1 and +1, and they alternate as a wave form. You could say the 1 is responsible for energy, the -1 is responsible for gravity, and the 0 is responsible for space, the medium for movement. So, in other words, a system of moving energy.

Every time a unit of space is added, it joins the system. The energy, in the form of quantum particles, is pushed by the gravity and clusters together, and the more pressure from the gravity, the more the energy vibrates, stabilizes and changes form, creating a cascading effect that can create explosions like the "big bang" that eventually become strong enough to outweigh the extreme gravity. Naturally, the mathematical interactions between energy waves continued to create more calculations, and the ones that were stable survived on to be duplicated again. Eventually, humans became a part of this moving energy system, and that is the sum total cause of our existence.

That, or it was aliens and we live in a simulation. But, then the above applies to them. It's inescapable.
