Vlad,
"all" ??!!
If a rainbow is an act of leprechauns then all physics lacks is the ability to establish the "Of leprechauns" component of act of leprechauns. The event or act, having happened in the physical world stands or falls investigatively. That's what you aren't getting.
You good with that?
The "default of history" is that non-naturalistic claims cannot be investigated naturalistically. Try again.
I suppose then the question is what is the 'non naturalistic' part of any claim. What Vlad is suggesting, I think, is that historians could investigate whether Jesus was killed, and was dead, and came alive again, and that could have been caused by a 'naturalist' cause such as sufficiently advanced aliens. If they could find out enough to establish that as probabalistically true, then it could be 'history' but the claim.of done by super/nonnatural god power would still be ignored.
If it was approached that way then any claims to events that in theory could happen would in the case of the Bible l, then be dismissed as not even hearsay evidence, and so unlikely, as to be some form of lie.
ETA IF we were to take this approach to the Miracle of the Sun which is much clearer evidence in terms of identiable known sources and due witnesses, it still gets dismissed as some form of delusion.
Indeed there are many claims that are effectively looked at like this such as alien addiction for which in terms of how we might grade evidence we have vastly more evidence than for the resurrection, and has no non naturalistic claims of causes attached.
