Thanks for the question, Torvicx. There are many ways to deconstruct this ancient misleading problem.
1) assume there is “nothing”, then this “nothing” would exist as “nothing”, thereby contradicting itself.
2) you can say things like “there is no dog here”, “there is no cat there”, “there are no trees in the ocean”, etc., ie you can deny the existence of certain specific forms of things somewhere or everywhere, but you can’t deny the existence of all forms of things.
3) energy conserves, neither created nor destroyed, including angular momentum — how much energy there is today, how much energy forever.
4) whatever exists is but a form of energy.
5) there’s no nothingness.
