Everything is in a constant state of flux, this causes interactions that manifest as both -- the macro entanglement is a manifestation of the micro entanglement, but it still occurs at the micro level.
Though a quantum entangled system has quantum properties in common over light years of distance, something macro-"entangled" systems do not have, you count their entanglement as similar to non-quantum systems.
All subatomic particles are constantly flipping between different aspects/states, entangled from one to the next through some extra-dimensional space/time or equivalent factor. This causes changes in the more macro environment that result in seemingly minor changes, but which cause macro tanglements
For what purpose?
Understanding. Free the thinking from static models to one of constant change rippling through space/time.
We know there are forces which cause stuff to clump together. No mystery there.
Or is there?
Those forces change when Neutron → Proton + Electron due to flipping quarks/leptons for example.
Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. For example, a proton is made of two up quarks and one down quark, while the atomic nucleus of helium-4 is composed of two protons and two neutrons. The neutron is made of two down quarks and one up quark. Composite particles include all hadrons: these include baryons (such as protons and neutrons) and mesons (such as pions and kaons).
Neutron (2 down + 1 up) → Proton (1 down + 2 up) + Electron (1 down - 1 up ?) in above example.
Written religion certainly trends to a static state ... unless it is open to interpretations. Oral religion tends to follow the orator/s interpretations. Dogmatic beliefs are virtually by definition static.
... Is our nature as thinkers to think good thoughts, bad thoughts or complete thoughts? ...
Yes, it is also a curse, if you will: the apparent inability to not-think.
... Do you separate your emotional philosophical thinking from your science mind or are you able to form a cohesion?
I don't think it is possible to separate one from the other. They are both part of your world-view, and information is processed depending on how it fits these fundamental (to each person) concepts. The less friction there is between them the easier it is to process new information.
In deeper space we find the signatures of other organics compounds: polycyclic aromatic hydrocarbon (PAH) molecules are the most abundant family of molecules in the interstellar medium after molecular hydrogen and carbon monoxide, ...
These molecules would likely be formed during nova type events as gases are expelled, expand and cool/condense into entangled molecules that are then be scattered in space.
... What is a pre-biotic chemical? ...
A chemical/molecule that is used to make/build biotic molecules, those necessary for life (amino acids for biotic chemical example).
The entanglement of these pre-existing pre-biotic into biotics means mixing in proximity to allow the further entanglements. Natural caldrons of puddles perhaps.
