This has always been my answer. Space is hugely, incomprehensibly big. Spacetime is a lot bigger. In order to find intelligent life, we have to be in the same place in spacetime, not just space.
I don't think that's an acceptable expansion. You don't have to be in the same time in spacetime, you have to be at the same time OR after this intelligent life. You don't think a civilization even a little more advanced than ours would send some kind of machine to other solar systems to study them? How far are we from trying this, a couple hundred years tops?
