This is a really difficult question and probably why no one has answered it yet.
I’m sure at school you have been taught that energy cannot be created, just transformed from one form to another. But it has to come from somewhere in the first place.I’ve done some searching online and the best answer I can find is ‘from the Big Bang’. But this doesn’t answer how that energy was created during the Big Bang. Although lots of scientists are trying to understand the Big Bang, there is a lot that we do not know about it.

Like Amy I googled this, the New scientist has some good answers on this.
The amount of energy in the universe is constant so it just changes form one form to another which includes matter.
One theory is that the energy in the universe is actually zero, with all the energy of particles and radiation being balanced by the negative energy of gravity, caused by the attraction between particles.
