Miller-Urey type experiments produce toxic chemicals, such as cyanide and
formaldehyde, but not amino acids.

Response:
Cyanide and formaldehyde are necessary building blocks for important
biochemical compounds, including amino acids (Abelson 1996). They are
not toxins in this context.
Miller-Urey experiments produce amino acids among other chemical
compounds (Kawamoto and Akaboshi 1982; Schlesinger and Miller 1983).
