If you increase the energy density (temperature) of a volume of space, particles therein collide with each other at higher speed. If things get hot enough, the collisions result in particle-antiparticle pair creation and annihilation. The hotter it gets, the fast and more numerous the particles become. The BB was a hot soup of such particles early on and, as it cooled, particles stable at low temperature were all that were left (by definition, duh). That includes the fermions we all know and love. The details of why there were apparently a net number of matter vs. antimatter particles left over is still being worked out.

the big bang was the creation of light through super neuclearic energy. The massive amounts of energy produced at the time set in motion several laws of physics. All points of life became possible at the time, through the various types of amino acids that were symotainiously formed and activated.
Then, also were the boson particles and fermions. But then again, I wasn't there.
