The question is ill posed. If there is incontrovertible scientific evidence, then they are already “physically” here. I presume the distinction the parent is trying to make is between some form of electromagnetic radiation, versus chunks of matter, but if it’s some form of signal, then they are interacting with us, physically.

We see them, they're far away, they are unaware of us or don't care. I see this as the most likely alien discovery scenario, because so far we haven't seen any, so they are probably pretty far away.
