answers your question whether the universe was designed for life. Obviously the whole universe is not to be packed with life but to ensure that whereever there is life it has quality. Seems resonable?!
I disagree with jar that this is off topic. But most of what you said is, if not off topic, unrelated to anything that I said.
The quoted text is a little closer to the topic at hand (and some of what you said earlier). Leaving many objections to one side for the moment, you still have two problems:
1) Most of the inhospitability of the universe is not needed to ensure harmony for life here. It the universe was created for harmonious life, it could have been designed a heck of a lot nicer. Ask the dinosaurs about the universe being harmonious.
2) The fine tuning argument still has issues. Either the universe was fine tuned for our existence, or we are fine tuned for life on earth. We have evidence that populations of living organisms adapt to the environment and we have NO evidence that the environment adapts to living organisms.
Until you can show this fine tuning mechanism at work you have no actual evidence for it. Do you have any evidence of fine tuning going on that could not be simply explained in terms of life adapting to the environment?
