(6,019 posts)That phrase is key. There is so very little we are able to observe in our own galaxy, and our understanding of this galaxy is still changing. We are only now able to sense (not see) near-earth sized objects within a relatively small number of light years from our planet. Still, weve already found hundreds with our feeble sensory abilities. Given our tiny time of actually being an advanced civilization, Im sure there have been many out there which have existed before us and there will be many after us. I think the markers are just too hard to see for us right now. We threw our own markers out, like gold records and Elon Musks car, but there wil almost nothing left of the car in a few years. Space is harsh.
To say were likely all thats out there, in terms of advanced civilizations, seems unlikely to me. However, making contact with any other civilization due to the gigantic distances between solar systems, galaxies, etc., is a huge hamper to our efforts.
