Where did the universe come from? Atheistic origin science has no answer.

[Sword of Christ]

Proof or shut the hell up. Surprisingly, your opinions mean jack shit to me without outside verification.

Same goes for your own unproven opinions then. Go on the better arguments, there are better arguments for God than atheism.

The moment theists start making solid, well reasoned and valid arguments, I'll let you know.

But you have been pounded by well reasoned and valid arguments in favor of the belief in Gods existence. Note I'm not saying you can "prove" God the way you're demanding. You can't.

Except that... mainstream science doesn't accept fine tuning... because the universe is not fine tuned.

Mainstream science doesn't accept fine tuning because it accepts materialist dogma. There's no other reason why it doesn't.

And, again, a non physical god that doesn't interact with the world is no different from a god that doesn't exist

He interacts with humanity on a 24 hour basis. Miracles are very rare events but God has constructed his creation in such a way that there will be some kind of a context that would allow for them. They won't be "violations" of the natural order but are parts of the same design. No there is no proof for this but like you said if God exists then it will have to be a God who interacts with us and revealed himself through human history. Specifically in this case through the person of Christ.

, and therefore, you have no possible justification for believing in it. At all.

I may as well say you have no justification for your belief in materialism beyond "what mainstream science accepts" which is an argument from authority not your own reasoning.

That's just the way rationality works.

You have been told that atheism and a materialist view of the universe is rational so that's what you believe. You haven't explained why you think it's rational beyond "because scientists say so". Scientists don't have all the answers they just have their own specialist subjects. Most of them haven't studied philosophy or theology and science is perfectly well compatible with God.
