The word sin in Spanish means without.

 

The idea that a human could be in a state without God is crazy if one's idea of God is a being without limits that is everywhere at all times. 

 

How could anyone conceive of being outside of everything, unable to get back in?

 

Perhaps someone seriously high on drugs, like say, a group of protohumans dining on psilocybin for many generations.

Locked in a cycle of first seeing God and the infinite fabric of time and space deconstructed and reconnected during a series of short circuits  across their right and left hemispheres (dexter and sinister)  and then the next morning, feeling like Hell and wondering, "Where did God go?".

 

And then one day, a shaman of one particular tribe saw these parties were getting out of hand and, if continued, could threaten the tribe's survival.

So this shame man told the tribe that this particular fruit was forbidden because it let you know God and led to knowing lots of others as well, some that might also be promised to the Chief or his brothers. Eating it would be punished by being expelled from the tribe. 

 

But it was too late, by the time this first philosopher could conceive of these notions of the structure of the Universe and how he might be connected or disconnected (sin) from all the other creatures who didn't seem to have his worries his prefrontal lobe was developed. He realized that eating the magic mushrooms had changed his people forever. Even those born who had never eaten the forbidden fruit were born different from the animals of the world. Where once they had roamed with all creatures in the garden now they could only see themselves as separate. They were now humans.

 

Consider the lilies of the field, they toil not, neither do they spin nor do they have a central nervous system by which to develop a cognitive network of experiencing existence and yet they get on quite well with each other.
