indistinguishable
Impossible to differentiate
Indistinguishable means impossible to tell apart.
Two things are indistinguishable when no difference between them can be detected: The forgery was indistinguishable from the original.
The word often appears with "from": His accent was indistinguishable from a native speaker's.
What counts as indistinguishable depends on the observer or method of comparison—twins indistinguishable to strangers may be obvious to their mother.
