I don't have theology. (Are you not understanding what the whole "atheist" thing is?)
Theology no, Belief certainly - atheism as expressed in "Scientific realism " is a belief set.
That nothing exists that you cannot observe.
That the patterns that do exist in what you observe (you call scientific model) will keep repeating without exception.
Which is odd, because all they are is observations. The turkey who observes that people are good and bring food every day is violated only once, around christmas!
You also cannot know whether you see a projection of reality from higher dimensions in which case all of science is empirical. Indeed since your philosophy of life is that senses only improve to what they need for survival actively disputes the idea you see all there is...
More assumptions.. That the abstract things in that model based on observation, map into real things in the universe. Phenomena and noumena.
Your concept of life is as a chemical automaton
That all life was a result of a lucky chemical accident to a first living evolving cell. Whatever that first cell was was a horrendously complicated thing!, it went ping from no life....
That your concept of consciousness is a chemical process confined to the automaton
That whilst the hardware of life was the product of random chance, the software of life wrote itself by accident!
And so on...
You have a complex set of beliefs. Sadly the real world chooses to throw curved balls of evidence that dispute some or all of that, but rather than investigate you would rather pretend they are not real!
There is evidence of something that was bread, turned red, now has all the characteristics of recently living heart tissue but only maternal DNA sequencable, the nuclear will not sequence.. Repeated. It turns most of the above belief set on its head.
It isnt conjecture like life from chemical soup.
