We look in our scopes searching for exo planets, I suppose if were possible that reason on it's own would be enough. But the likelihood of faster than light travel (theoretically ATM) would put a damper on it.
If we were to see and with radio astronomy detect advanced civilisation, it would many thousand of year to receive the signal. By then they may have invented FTL travel and may beat their own radio signal to get here.
