There is no known cause, other than intelligent design, that can produce machine-like structures with multiple interacting parts.
The evidence of purpose and design permeate life at every level, and this evidence presents ever increasing challenges to all theories of undirected evolution.
Its unique properties allow it to fill many roles throughout the biological world, from forming the matrix of our cells, to regulating the temperature of our planet.
