Something rather than nothing

Why is something rather than nothing? Universe is not an empty place. The hardest questions ever are about size and infinity of Universe. Or age. Is Universe infinite and was before an empty dark space? I mean before Big Bang. If yes, what is then energy? Is an energy something like simple physical quantity or more sophisticated value which switch on and create various entities in Space? Did energy appear before starting processes of Big Bang? Did energy exist before? If Universe has start, what happened before if there is something rather than nothing?
Energy can be explanation why all Universe exists. Any type if energy rules the world. I believe energy is intelligent power which is able to create inorganic and organic structures. Is then energy behind creation of all Universe, time and mass? And where energy comes from? Scientists described Universe as expansive area which will expand continuously in far future. At some point in past all Universe was in one place and started by Big bang. But what was before Big Bang is not well explained till now. Scientists say time didn't exist before Big Bang. But term 'there is something rather than nothing' clarify it was something before Big Bang. 'Nothing, no age before Big Bang, no Universe before Big Bang' simply can't be true formulation. Universe simply exists. If it's infinite, then existed forever. But yes, its shape was changed during existence. Maybe time is infinite, too. I believe infinite Universe exists because of functions of energy as movement, creation or repeating, multiplying. I also believe infinite Universe means existence not from point A to point B, but forever in some circle of occasions happening all the time without end. That makes completely sense. Universe exists thanks to sequence of events and energy existed forever. It doesn't make sense if there is a complete beginning and end. Then nothing has meaning in Universe.
The cycle as creation certainly is a fact, we
have galaxy in which is created stars and planets with moons and on some
planets is also created life. And life of Universe is not a simple issue but
very sophisticated issue with complexity relationships among them. I see in
this big meaning. People because of this created a figure God in past. But we'll
think more on Universe as creator itself with big help of energy as partner
which lasted forever in infinite Space. Because there is something rather than
nothing.
