Copenhagen Interpretation

The Copenhagen Interpretation of Quantum Mechanics says a particle doesn’t have a position until position is measured. Can someone explained what’s meant by “measured”? I can’t believe it means measured by a person or their instruments, which is so completely anthropocentric (or in general life-centric). Or do CI theorists actually maintain that prior to life in the universe, no particles had specific locations? And to add to this notion, if particles have no specific location, how exactly do macro-objects made of those particles have a position even though no one has “measured” the particles or the macro-objects.
