You said that "energy was created" and it can't be created. What does this have to do with it?.. initially no matter particles existed or could exist perhaps only fleetingly. According to prevailing scientific theories it was at this time that the forces we see around us today merged into one unified force..
In the second phase, this quark–gluon plasma universe then cooled further, the current fundamental forces we know take their present forms through further symmetry breaking – notably the breaking of electroweak symmetry – and the full range of complex and composite particles we see around us today became possible, leading to a gravitationally dominated universe, the first neutral atoms (~ 80% hydrogen), and the cosmic microwave background radiation we can detect today.
