What makes people irrational thinkers?

[Angrboda]

Is properly basic to consider physical reality non-contingent? I am okay with that but IMHO that also is an unsupported opinion.

That's not entirely true as there are scientific theories about how the universe can avoid the contingency problem. So while I think the contingency of the universe is an open question, it would be wrong to say that it isn't or can't be supported as being non-contingent. And I think the reason that contingency is so important to theists is that it leads to the intuitively appealing arguments that if the universe isn't necessary, then something else must be. That seems not much more than an appeal to ignorance as well as simply kicking the can down the road. Particularly as most theist answers to the contingency problem are little more than explaining it away with magic, which is no explanation at all. If the contingency issue can't be resolved by an appeal to orderly and predictable processes of some sort, then we really can't offer a rational explanation for the universe. But "a god" is not an orderly and predictable process, so god(s) as an answer is no better than "it just is" or "it just happened," which beyond not being intellectually satisfying, is basically vapid.
