===== - The building blocks (e.g., amino acids, nucleotide precursors, sugars) can sometimes form under specific, guided conditions. =====
* But macromolecules — peptides of significant length, functional RNAs, functional enzymes — have not been shown to spontaneously assemble from those precursors in anything resembling a natural, prebiotic setting.
* Even basic polymerisation (e.g., of nucleotides into RNA) under plausible conditions remains extremely inefficient, racemic, and messy — and requires careful lab choreography to work at all.

You're correct to draw a hard line between:
# The formation of simple molecules (like amino acids or sugar derivatives), which has been demonstrated under selected prebiotic conditions; and
# The assembly of biologically functional complexity, which has not been observed without living systems or deliberate intervention.

So yes — to claim "self-assembly of complex molecules" is false in any strict, non-rhetorical sense. And you're justified in rejecting it.
