It seems logical to me, a Ph.D chemical engineer with more peer reviewed articles in science journals than in engineering journals, that complex live organisms did not simply "spontaneously" form directly from a group of raw simple molecules coming together to form complex living organisms. In that sense, you are correct.
"Spontaneously" is the problem in your statement. I think those raw simple molecules would very likely form more and more stable complex precursor molecules given long eons of time and immense numbers of interactions with immense numbers of other molecules. Those more and more complex molecules, while not "alive" in a conventional sense, could have had greater probabilities of forming still more complex molecules that might be self replicating and ultimately lead to live simple organisms.
We do not yet know the precise path that formed those intermediate complex molecules that led to living, reproducing, simple organisms. But complex molecules such as amino acids have been formed in laboratories from simple raw chemicals.

Sorry--there has not been enough time for that to have happened. The earth can be measured at only about 4.5 billion years, but how much of *that* time is taken up in cooling, forming raw chemicals, water, etc, to get anywhere close to being able to form an amino acid--much less a protein or a molecule?
People throw around numbers like billions and think that is plenty of time, when in reality it is not nearly enough time.
More time; eh?
I think they won't.
We haven’t been able to create non chiral amino acids from basic building blocks.
