"We are certain that it’s [consciousness] not a physical aspect of our body (obviously), so, this might be the software part that runs everything in our bodies effortlessly."

I am not certain though. :)
For example if artificial intelligence will be equal to ours or even surpass us, would you also be sure then that there is something not physical which makes it think - and yes - have a kind of consciousness? Are wandering electrons and ions in our brain (or the processor of a computer) nothing physical? Would you also call software 'not physical'?
We also have kind of a 'program' that lets us grow: the genes and their regulation (of course combined with environmental influences). But yes, these genes exist in a physical way.
Maybe there is kind of a "big programmer", the "great physician" (some of us would call it "god"). I cannot know if someone has initiated the beginning of the universe and development of living creatures intentionally for some purpose. Maybe it was a great but very lazy programmer and therefore he chose conditions where by evolution new computers (organisms) would create themselves automatically. :)
Will we discover who "it" was? Will Microsoft Windows one day know who Bill Gates was? ;-)
I cannot answer to your questions but they are very interesting and obviously stimulated my mind ... maybe once I will write an article about that too.
