abiogensis hypotheses are just this.
Now we have had the theory of evolution and its projection for over 100 years, with all the modern understanding of life, biological systems, and still there is not a good actual model of how it worked.
Correct, although you're comparing apples with oranges. The ToE, as Darwin & Wallace described it, was at the scale of individuals and populations; a molecular basis for heredity didn't come until the 1940s. Abiogenesis research is necessarily molecular, and wasn't started until the 1950s.
There's also the problem that we don't know the environmental conditions under which life got started, and we don't have any examples of what the earliest life was like; whereas we know the conditions for, and have many examples of, current life.
We can artificially create part of the systems of life, but this creates massive manipulation and very controlled environments.
Only in as much as we have to simulate plausible early Earth environments in the lab (it may be necessary to explore potential chemical pathways outside the early-Earth regime, but only with a view to discovering the chemistry required).
So being truly scientific, life creation must be very rare and very unusual.
That's not a scientific statement until you know how life arose. But it is quite plausible that it occurs very rarely - but you should also consider that, given enough time and opportunity, even the most unlikely events will happen. In this case, we have hundreds of millions of years and a whole planet of opportunities
working at a molecular scales and speeds. If that's not enough opportunity for you, also consider that from the Kepler probe observations there are estimated to be around 19
sextillion (19,000,000,000,000,000,000,000) Earth-like planets in the observable universe on which it could potentially occur.
At what point one admits it is actually a creative act.
Depends what you mean by, 'a creative act' - does the formation of a snowflake count? a galaxy?
Saying this does not admit who or what did the creative act, just it happened. Is this such a hard thing to admit the possibility of?
Scientists are quite happy to accept that it just happened - because it clearly did happen(!); they're just curious to discover the mechanisms, i.e.
how it happened.
I am happy to admit life could be a system of some sort without a consciousness that I understand or could define...
Not sure what you mean by this - the vast majority of life does involve systems without consciousness.
