You have been given an almost irrefutable answer to your question
Okay, I'm going to forgo you emotional outburst for now and pulverize your "irrefutable answer" since I had no idea you entered this as a debate. And narcissism that leads to blind ignorance shouldn't go unchecked, at least not in good conscience. And since your emotional charge caused me to look again at your scenario, I have no shame in reevaluating my previous opinion.
1. The variance you suggest is illogical from the start. If the successful brother comes back with food consistently then the variance of the food "not being there" is nonexistent and your premise is faulty.
2. For exiled nomads to meet up and tell of their experiences in the manor you suggest, seeing, a wolf, feeling wind, looking at trees and then deciding those things were "otherworldly" experiences because they couldn't hunt and so they unanimously give rise to a 'God' concept is ludicrous. The successful caveman could have just as easily used the variances in your scenario as a positive and said "the gods favor me."
3. 99% of people do exactly as I alluded to when I said logic dictates they would search for an answer that will solve their immediate problem. We see it everyday in life. I've been through it myself. Someone gets rejected at a job interview. I'ts been going on for more then a week or two. He begins to feel as though the world is against him. He makes excuses that are bogus but yet make him feel better about himself. The reality of hunger causes him to examine himself more objectively and realizes the negativity is coming from him. Everyone he meets is confident they should get the job at the interviews but he isn't and realizes it shows. He works on his attitude and in days he lands a job.
The caveman realizes the variances that are causing his hunger isn't the wolf, the wind or the lack of prey. Its in his individual ability to apply the same skills of hunting as his brother. So he looks at himself to see what he is doing different and corrects it. We call it " pulling ourselves up by the bootstraps." To think that people create an excuse and starve is the epitome of naivety.
I think it's very selfish to ask questions and continue discussions in a seemingly open manner to trick people into addressing your questions logically, all the while having an agenda in your mind.
This seems to be how smiling door-to-door Christian salesmen operate, which is why they are so readily detested.
This is the purety of faith? Torture logical people until they can no longer cope with reality?
And you have the gall to say I have an agenda? And I suppose the logical fallacy of a scenario riddled with holes is reality to you?
And regardless of what you say or do in here, the truth is, you and I both know it has threatened it, has shaken it, and causes you to squirm emotionally.
Ah, no. But I do wish you a peaceful existence.
