The junkyard tornado argument uses a calculation of the probability of abiogenesis based on false assumptions, as comparable to "a tornado sweeping through a junk-yard might assemble a Boeing 747 from the materials therein" and to compare the chance of obtaining even a single functioning protein by chance combination of amino acids to a solar system full of blind men solving Rubik's Cubes simultaneously.
However, what the junkyard tornado postulation fails to take into account is the vast amount of support that evolution proceeds in many smaller stages, each driven by natural selection[8] rather than by random chance, over a long period of time.
The theory of evolution has been studied and tested extensively by numerous researchers and scientists and is the most scientifically accurate explanation for the origins of complex life.
The argument is then to infer from the huge size of the phase space that the probability that the entity could appear by chance is exceedingly low, ignoring the key process involved, natural selection.
This is comparable to the older infinite monkey theorem but instead of the works of William Shakespeare, the claim is that the probability that a protein molecule could achieve a functional sequence of amino acids is too low to be realised by chance alone.
