The ONLY way we get input!

Not through magic waves, not through voices of the dead--through our nerve endings.

The ONLY afferent signals we can process are composed of some form of energy--light, heat, chemical, pressure--that is translated into the chemical and electrical energy processed by our nerves.

And we have four efferent pathways, all mediated by the same chemical and/or electrical energy: sympathetic & parasympathetic (autonomic), motor (voluntary), and endocrine (hormonal).

The carefully and successfully evolved neuroendocrine system is elegant and more than sufficient to navigate our complex relationships with each other and our environment--no "magic" need be invoked. And that spark of life--the spiritual part of us--can also be explained by this. 

As to the ORIGIN of it all--"Let there be light!"
