Are We Detecting Potential Signs of Life in the Universe?

debates about what is or isn't an indicator of life in the univers happen all the time. We did not have the capacity to detect potential signs of life, these bio signatures, even 50 years ago. Now we stand on the cusp of being able to see a bio signature and then go check it out for ourselves. Is that really a sign of life, or is it just another phantom in the wind? Phantom in the wind. Ok, so we have been talking about humans searching for alien life. But i want a switch tack now and ask, you know, what if the aliens are king for us?
