Maybe, but I guess that I just hope that we don't find "concrete" evidence of past alien life, because it would point to the great filter being ahead of us, but there is still a good chance that it is ahead of us as a civilization. What creeps me out is the Boötes void, it's a huge area of space apparently devoid of galaxies, but maybe it is home to a super advanced civilization who have harnessed the energy of all of the galaxies. That's just speculation though, but it is still very creepy nonetheless.
