Yes, it's very clear, thank you. On the other hand, I believe the very core of science is to use our imagination and creativity to look for things that don't fit any models, that are not accounted for by any of them, for higher-order structures that might explain the current models better and so on. For example, our civilization is more or less built on energy, with the electric current as its main medium, so we are totally dependent on external energy sources - and that's currently the main problem of our civilization. It's not impossible other civilizations might exist (in other space-time environments) that somewhat learned to achieve similar results we do (transportation, healing, distant communication) without using external energy sources. This would at least account for lack of artefacts we currently identify an advanced civilization with.
