F2. Intelligent life exists. This is a foundational claim of theism. Theists believe the universe was intentionally caused and designed for intelligent life. Mindless naturalistic forces don't have to cause any life or intelligent life.
Intelligence life exists, to the extent we define ourselves to be intelligent. This I will accept. Cartesian. I think, therefore I am.
F3. The universe is fine-tuned for life. For the belief the universe was intentionally caused for life to exist it must be in a configuration that allows life to exist. No one can claim intelligent life had to exist. No one would predict or expect mindless forces minus any plan or intent cause life to exist. This evidence is so powerful it's the basis of multiverse theory.
Here I have to break company with you, because it does not appear to be so. A fine-tuned universe for life would, in my view, have much more life in it than we. We live on a speck of dust -- one of 8 or 9 big specks with hundreds or thousands of little specks, circling a rather insignificant star out of 100s of billions in our galaxy which is one of hundreds of billions in the known universe and there does not appear to be much space dedicated to life, much less fine-tuned for it. 99.9% or more of the mass of our solar system cannot support life at all and is openly hostile to it.
As far as we know, on our small speck of dust, we are perched precariously, in a fragile bubble, that will only carry life for a small fraction of its total existence.
The multiverse theory is a way to explain how life can come to exist unguided. Give enough monkeys enough typewriters and one will type out the Lord's Prayer. So, if you have a near infinite number of universes, it's not surprising that one would have life in it - on a small speck of dust in an old backwater of a outer spiral arm of a rather innocuous galaxy.
F4. The fact the universe has laws of nature, is knowable, uniform and to a large extent predictable, amenable to scientific research and the laws of logic deduction and induction and is also explicable in mathematical terms.
Sure, but there is no actual proof that a universe needs a conscious creator in order for there to be knowable laws.
Theism is a belief, an opinion. This doesn't prove we owe our existence to a Creator. It is evidence. that favors that belief.
Well, okay. To each his own. As an atheist, I would respond just with "I don't know" how the universe was created, or even if it was created. Maybe there is no such thing as nothing, and the universe always was and always will be, only changing in form.
