Your misconception is common in this line of thinking. You're confusing evolution with concepts like abiogenesis or panspermia. To put it another way, the Miller-Urey experiments were not testing evolutionary hypotheses.
I have no misconception as to what the TOE claims. The methodology of selling the theory has evolved over my life time. See now to seduce as many Christians as will the 'origins' of a hot steamy pot of primordial soup got compartmentalized off to a dead end labeled abiogenesis. My guess is because this steamy pot could never be produced, let alone tested, the claim of its ever having existed got sent off to another world.
The most all this 'testing' can a test is the commonality of substances used by the Creator.
