Non-scientist here (but Ph.D). It defies logic that unimaginable complexity such as found in the “simplest” of organisms could spontaneously arise. This is the death knell of evolutionary theory.
And also why I knew at age 5 and continue to know at age 59 that it is not true.
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.
