To say there's no purposes in nature is philosophy and intuition.
It's also a leap of faith. In my opinion, the proper way to phrase it is that there is no evidence that nature was created by an intelligence for a reason.
Yes, Baha'is believe in the God of Abraham, but that is different from saying we believe that everything in the Old Testament that is written about God is actually true. I cannot speak for all Baha'is but I do not believe in the stories in the Old Testament that turn God into a man.
I suppose that your criteria is what Baha'u'llah taught, and that you believe all of that without editing. It's interesting to consider how much of that Old Testament description of Yahweh can be disregarded and still consider it the same god, which is analogous to deciding how much of the New Testament description of Jesus can be disregarded and still call what's left a(n) historical Jesus. For example, if everything said about Jesus except the supernatural and miraculous happened, we could call that the New Testament character but embellished. But as one starts adding to the I-don't-believe list - for example, "I don't think he had apostles, or came from Nazareth, or gave the Sermon on the Mount" - at what point is it no longer that personage?
This is a variation of the sorites paradox, as when we ask how many hairs have to fall out of a head to call it bald, or what day did a bald person go from not bald to bald. When does the god of Abraham become the god of Baha'u'llah?
The big hinderance in determining what is logically possible in our system synthetic to the real world is that we do not know all the defining elements, properties, and rules of acual reality, of what we want our "Real World" abstract system to remain synthetic to.
It sounds to me that what you are referring to is the subset of logically possible that is actually possible. If so, I agree. We have no way to decide in many cases whether a proposition is actually possible or merely not yet known to be impossible.
If something is impossible then it cannot be logically possible.
Agreed. All claims of fact are one or the other - known to be impossible or not - that those not known to be impossible are by default logically possible, and that no claim is both or neither.
Your position would have us freely put all that is infinitely impossible into the set of that which is possible
I don't know what infinitely impossible means, but yes, I call things possible until they are known to be impossible. Suppose Maria died this morning. You were expecting to have lunch with her, and she is nowhere to be seen. You consider the list of possible reasons. Maybe she forgot or her car broke down. But these things were in fact impossible if she's dead. Is it wrong to call them possible before you know that they are in fact impossible? I say not. It is in this sense that we can use the word possible to refer to the impossible.
You mean that you do not understand the purpose.. It does not mean that there is no purpose.
No, it does not mean that he (and I) don't understand the purpose, which presupposes that there is one. It means that if an intelligent designer with a purpose exists, we don't have sufficient evidence of it to believe that at this time.
You can claim that the rain has no purpose, but many others would disagree, and see that it DOES have purpose.
Why would that matter? You likely make that claim, but it has no persuasive power without an accompanying sound, evidenced supporting argument.
Of course people can deny that there is a purpose
Once again, the proper claim is that there is no apparent purpose. That's different from denial, but very similar to the problem with the claim of so many theists that atheists say that there is no god when what agnostic atheists say is that there is insufficient evidence for one to justify belief. It's the same distinction.
If people think that life is just a game that ends with death, then they are in for a shock.
You don't know any more about what follows death than I or anybody else does. You believe by faith and so make unfalsifiable claims as if they are fact, but faith is not a path to truth. It's guessing. One believer guesses that one set of unfalsifiable claims are correct and another of a different faith guesses that a contradictory set are correct, both claiming to have truth and knowledge when neither has either.
I have plenty of evidence, but I can see that it is not worth discussing with a person who denies the significance of existence.
Your evidence doesn't support the conclusions you assign it.
"You find that people cooperate, you say, 'Yeah, that contributes to their genes' perpetuating.' You find that they fight, you say, ‘Sure, that's obvious, because it means that their genes perpetuate and not somebody else's. In fact, just about anything you find, you can make up some story for it."
- Noam Chomsky -
Can we assume that you understood Chomsky's flippant remark to mean that according to him, the theory of evolution has insufficient evidentiary support? If not, I don't know why you cited it. Chomsky sounds like a creationist there, and there's good reason for that. His pet theories on the evolution of the linguistic faculty were at odds with mainstream science. He appears to believe that evolution is not explanation enough for that, but I haven't seen his argument if he has one. You can read a bit about that conflict it
here.
I know by experience that if people do not want to acknowledge truth, they will not.
I don't accept your definition of truth for myself. What you have is what I call fervently believed intuitions lacking sufficient evidentiary support to justify belief. You'll need to go down that second path to generate what I'd call truth. You should expect other kinds of arguments to be rejected.
Any intelligent person can understand that we have intelligence for a purpose.
Here's another of your unfalsifiable, fervently held beliefs that you offer as fact. A more intelligent person understands the limits of knowledge, both his own and that of others. I know that you are guessing even if you don't.
