To create anything at all, energy is required. Think of a power plant powering a city. The city is powered by the energy conveyed from the power plant. However, the power plant still needs fuel, and that fuel needs to be made, probably at a factory or by people (or both). The people and the factory require energy to be created, and so on. For anything to exist, it has to contain energy from another source, and as I said energy doesn't spring up out nowhere.
The problem is, there can't be an original source of energy, because it would require energy to exist, as well. And so on.
It also can't be a cycle such as I suggested earlier. Imagine the circle. It has energy flowing through it, because of the cycle of universes going on inside it (the cycle requires one universe's leftover energy to power the second, and the second the third, and so on until it comes back to the first). Now 'step back' and 'look at' the circle from a distance. Energy is flowing through it, but where did that energy come from? Say a plane of existence. That would still require energy, as I said above. The problem of the original source of energy arises again. The circle become a 'knot' in a line.
