Is it intelligent to make the cutoff "exact same as ours"?

It has to be the exact same as ours. I’m saying, obviously hypothetically, it’s IDENTICAL to us. How close would we have to be to be able to detect life exactly as it is on earth?
Like I’m pretty sure if the second earth was ten light years away we would be able to detect radio waves with SETI instrumentation.
200 years ago we weren’t transmitting radio waves so from 200 light years away no technology could hear what hasn’t arrived.
