Why can't consciousness come from material things? We only have evidence of one kind of substance, which is material substance.
Some of Max Tegmark's writing as well as Lawrence Krauss' have describe gravity as the "cost" or the thing that is balanced by the expansion of space.
The expansion of space having been driven by another as yet undescribed field.
All things are physical. Consciousness is a side effect of information processing. Seems like we just have fundamentally different assumptions about what can be a valid belief.
I don't just disagree with you. I think your belief about consciousness isn't even well formed. I don't even think there could exist evidence to support a belief like "consciousness creates matter".
