So so glad you don't define what science is... fine-tuning for life is mainstream science....and actually well documented and peer reviewed. you might want to read up on it... heck even use the lefty libbie Wiki :If so, you have conceded the point, and demonstrated that by your own criteria the idea is unfalsifiable. Sloppy sloppy sloppy....The question is, which is more important to you: your idea of falsifiability, or your new toy of fine tuning. By your criteria, you can’t call both valid science.
Physicist Paul Davies has said, "There is now broad agreement among physicists and cosmologists that the Universe is in several respects ‘fine-tuned' for life". However, he continued, "the conclusion is not so much that the Universe is fine-tuned for life; rather it is fine-tuned for the building blocks and environments that life requires."
I have to wonder now just how your criteria for science must fit with the broad agreement that shoots your thinking down. (and that is from real scientist and not a chat room troll)... I'll take the broad agreement by scientist over the chat troll.
