Did you actually READ the

It is all very simple.
Life is everywhere buzzing
just like electrons around atoms

The religious leaders have various routines to keep their power and palaces,
suck your money and wash you brain and force you into obedience
Take a step back.

Our lifeform has evolved something called 'ego' to protect ourself.
We are not that more complex than that sunshade with photo sensor that has a voice added
so when the sun shines it says 'sun', I am closing, and if no sun, I am opening.
That, in short, is all consciousness is.
Never the less we are all connected, these days via radio and teefee too.
