And it could be right and if you don't know then what is more sensible and reasonable to believe
I seem to have to repeat this fact over and over again with you people: Without KNOWLEDGE, NO BELIEF is reasonable. So, the answer to your question is: None. No belief whatsoever until knowledge, one way or the other, is gained.
and what is the case for God (I defend only the biblical God and will argue against any other as being nothing but the construct of the imagination)?
Lmao that is hilarious dude. Your god has no more proof or evidence than any other god ever claimed to exist, yet you say all other gods except yours is a delusion? I took you for a more reasonable person than that, but clearly I was wrong.
To answer your question: Same answer for your god.
Since you are a philosopher the question is how does a universe materialize naturally and which natural theory or paradigm (or the one you support - what is it?) is right if any?
Being philosopher doesn't give me some magical ability to divine information out of thin air. I don't claim to know how the universe came about, and I'm not stupid enough to blame something I can't explain on something equally unexplained(like theists do). See, I'm a sane person, so I only claim to know things that I actually know.
If you can't say, then I see you divorcing yourself from the subject under discussion since you have made a judgment above.
Absolutely not. I say you're all delusional. That keeps me firmly in the subject.
Regarding evidence, the problem is that none of us were there
DING DING DING!!!! EXACTLY!!!! And that little statement right there, my friend, defeats everything else you said. You CANNOT KNOW, so stop acting like you can.
As an atheist, your worldview would see life coming from the non-living since you do not ascribe it coming from a living Being - God, would it not?
What the hell? No it wouldn't? Being an atheist means you don't claim to know where shit came from, not that it came from nothing. I don't try to answer things I can't answer dude. I go out and gather information so that I CAN answer it. Currently, humans have no ability to say where this universe came from, if it came from anywhere at all.
