Barely most certainly applies. You have the situation exactly backwards. The percentage of the universe that has been even partially explored is essentially zero. I asked you once before where you got this incorrect notion that we have a "survey pole for life than goes back in time 15 billion years". We have barely looked anywhere beyond the Earth for signs of life. Scientists have barely started to look for signs of life on Mars, and even there the answer remains "we don't know". Scientists have speculated about the existence of life in our solar system outside of Earth and Mars. Europa, for existence, looks promising. These are speculations, mind you. Whether life truly does or does not exist in our solar system, exclusive of Earth and Mars: We don't know. How can you possibly claim we have a survey pole for life that goes back in time to 15 billion years ago when we don't even have a survey pole that goes 20 minute back in time (light travel time from Mars to Earth at conjunction)?
