Excellent topic...
I've always been an advocate of consciousness created reality. Modern science is leaning toward this concept as well. It seems simple to me...without your observations, nothing can exist.
Quantum physicists disagree on what 'mechanism' provides the foundation for reality...though they agree, somewhere in the equation "a miracle" occurs.
The Copenhagen Interpretation, developed primarily by Neils Bohr and Werner Heisenberg, states basically that there is no deep reality. It divides the world into two categories...quantum entities and measuring devices...without one, the other can not take form.
All very interesting...imho.
