I believe that the human consciousness can be proven mathematically to be made of matter, not anything spiritual, through already performed relative velocity and gravitational time dilation experiments.
If it were spiritual it would be exempt from the laws of physics. This is not the case. If it were we would all be mentally trapped inside an eternal stillness, fully aware of our surroundings but unable to make the matter in our bodies move at the same rate as our consciousness is able to perceive the movement.
If one were to argue against this and say that humanity has a spiritual consciousness, it would not change the fact that the perceived movement of the consciousness can be slowed down or sped up relative to the space time conditions in which a humans brain exists. Thus, you would be arguing that there is a God, or a spiritual entity of any sorts, and that he can be imprisoned within extreme relative velocity space time and/or destroyed with the appropriate gravitational conditions.
Evolutionary debate is for amateurs. Biology, archaeology, geology.. bleh.. that's all settled and done with. Physics has all the real answers. You may have just read this and thought it a bunch of blabber, but if you take the time to understand the concepts the ramifications are pretty profound.
I understand that the laws of physics breaks down at the speed of light, therefore while physics can provide some answers, physics ain't the end all method of proving anything.
So no, physics doesn't hold THE answer, let alone any real answers.
