Lavoisier was the first to clearly formulate the law of conservation of mass, and Leibniz the conservation of energy. Einstein's theories showed that measures of mass and energy are relative (movement matters) and coupled with the ideas of quentum mechanics showed that mass and energy are also interchangeable in some circumstance. So it is wiser to talk about the conservation of mass-energy.
And indeed the big bang - the origin of the universe - was an explosion of energy and not mass. The reason this explosion of energy occurred is not known - and it may in fact not be possible to know. This is because the big bang was what is called a singularity - a point beyond which no observations can be made. Hence we cannot trace the laws of physics through it.

Einstein said that energy cannot be made or destroyed, it just changes forms. Matter is a form of energy. Matter exist because the universe is made of matter. Why the universe exist is a subject for philosophers and not scientist.

E=mc^2 states that energy and mass can convert into each other.
The First Law of Thermodynamics states that The sum total of mass and energy in the universe is constant.

Mater can't be destroyed but it can be changed to energy but will not be destroyed.
