About a half a million years after the big bang, the cosmos began to cool, as it cooled, the hot subatomic particles that constituted the early universe began to slow down and stop colliding with each other long enough so that protons, neutrons and electrons could form. The universe cooled further and the hot particles slowed further still allowing these particles to stay together long enough to create atoms.
