No one can say what woulda coulda shoulda maybe theoretically possibly happen in the right imaginary conditions in a universe with no God! Nor is that science! Religion.
There are no conditions, except in religions and in fantasy, where dust can naturally turn into a living adult human. PERIOD.
I am talking about “natural” (eg “naturally turn”) as in “nature”, not supernatural, which’s what Genesis 2 claimed to have happen with creation of man from dust.
Dust is byproduct waste, and “waste” as in dead or non-living matters. Dust is what break down of matters.
And when dust comes from a former living creature, when it break down into smaller particles, by decomposing, oxidizing, and drying out.
Dust don’t just magically come to life or come back to life.
There are no conditions, in which nature will turn dust into living adult human, like Adam in Genesis.
