I think what you're saying here is your personal interpretation of what Spinoza said, and not literally what he said. "Spinoza's God" doesn't necessarily denounce evolution.
I am not necessarily denouncing it either.I believe the answer to existence of life lies in a force of energy itself.
I will be simple here with thoughts but just off the top of my head.
Possibly in the beginning energy becomes trapped in resistance to itself and causes explosion.Through explosion repelling energies are trapped together in matter.
As they repel matter changes form to a substance it can more easily move in. It becomes gasses and water. As it still tries to escape it(Because two opposing energies trapped together) becomes life where it can move even more free.Now the matter itself is more easily movable.
As humans we have a sense of good and bad ,positive and negative,. We are conscious energy trapped inside of body( materialism.)
Who is really controlling who?
We are always finding ways of controlling energy through scientific technology to make life easier,communication unlimited,get to our destinations faster etc. As this technology increases so does our pace of life!
I am really curious as to how we know who is in control. We use energy through material objects to control it , manipulate and come out with a desired effect but what (energy force) is driving us to do this!
Is it possible that energy has a natural course to travel the path with least resistance so wanting to travel in and out of form as easily as possible , knowledge evolves as energy tries to make its way?
Can everything fall up under a law of nature.
You ask me to describe energy in definition and all I can say is anything you possible can observe is energy in it's state of least resistance in that particular instance!
Is it possible that all of the complexities we know of in life with all of it's laws of logic can fall under such a law of nature as the beauty of simplicity?
I know its out here because I thought of it off the top of my head but my point is that all existence is the result of energy that got trapped against itself and through repelling forces from each other all forces of nature were created as it works its way free and always takes the path of least resistance.
I don't believe the magnetic field of the earth effecting animals is coincidence but may play a role in all of life.
