So then we're experiencing a lag of at least several thousands of years of being able to hear or see evidence of alien life in just our galactic neighborhood. Which I understand is miniscule time on a cosmos timeline, but still seems improbable to me of being able to detect life. As in, I don't think not hearing or detecting alien life doesn't imply they don't exist 🤔
