I understand what you are saying, but I don't think you understand what I meant. I was critiquing the "100%" statistic. With all of those observations based on current spectrometer testing techniques that can only offer estimates and glimpses, we can not say that there is definitively 100% chance of life on the planet. In a few decades, maybe, but not now. You've made that clear in your above post. I think Vogt wanted to hype up the media for this discovery.
