How can you declare an issue “closed” or “proven” that has no final disposition? They are saying, for instance, that Venus can never support life. Yet back in the day, THIS planet was made up of exactly the same conditions that exist on Venus right now.
A couple of years ago, they were declaring that Titan and Enceladus were dead and incapable of supporting life. My, my how things change when they put new lenses in their tunnel vision glasses.
I have no idea WTF you think you are bloviating about.
