Well I tend not to overcomplicate stuff, I´ll I simply define/understand evidence as anything that supports a proposition/claim/hypothesis/theory etc.
It looks like you're still conflating what should be called evidence and what is it evidence of, which is oversimplification, not overcomplicating. It might behoove you to take a moment and think about that distinction, and then modify your use of language accordingly. If you have reason to disagree with either of the following -and by now you should have expressed that if you do, since I've explained this twice now already -please address that now:
evidence - whatever becomes evident to the senses; something is there, but what, and what does it imply?
evidence of - what that which is evident signifies
Obviously using valid reasoning would be a valid bonus, but it is not indispensable
Yes, it is indispensable, but only if you want useful (sound, correct) conclusions. I refer you to arithmetic again. The addends to be summed are the premises, analogous to evidence. What do they imply? A correct sum. How do we determine that? Using the valid rules of arithmetic (rules of inference). If we vary from that, we get an incorrect result. Misadding even one individual sub-sum (7+5=11) plays the role of logical fallacy, and the erroneous sum that results is a non sequitur. It didn't derive from what preceded it.
What we are doing when examining evidence is analogous. If all of the steps between the start and finish are valid - no "misadding" - the conclusion will be correct. To do this, one must learn those rules and adhere t them faithfully.
If X supports Y then X would be evidence for Y
Agreed. But to determine whether X is evidence of Y, one must apply valid reason to X and derive (deduce) Y.
But anyway…..by your standards………….why do arguments like the fine tuning argument fail as evidence for God? What “invalid reasoning” or “logical fallacy” do you think is being made? This question assumes that you reject the fine tuning argument as evidence for God…………if the assumption is wrong, then the question doesn’t apply
The fine tuning argument does support an intelligent designer, but it is also consistent with naturalistic explanations for why our universe is the way we find it, and naturalistic explanations are preferred because they are more parsimonious. They only require that nature exist. Supernaturalistic explanations require both that nature exist and a supernatural realm with a supernatural intelligent designer, something for which we have no evidence.
You can go on making this even less parsimonious if you like and add extra conditions, like a super-supernatural realm with an even more powerful intelligent designer that created the one you believe in, but you can see why that is not helpful and not desirable even though we cannot say that it is impossible. And just as you won't trouble yourself with that third level of possible reality, because why should you, I don't trouble myself with the second layer for the same reason. If there is more to reality that either of us know or believe, it can wait until we have a reason to seriously consider it before so doing.
Incidentally, fine tuning is consistent with a deity, but not an omnipotent one - the kind you believe in that creates the laws of physics and all of spacetime and its contents. Why? Because you're describing a deity constrained by a higher reality, one which it must discover and incorporate into its creation so that it can build a universe that works like this one.
Fine tuning is also consistent with a multiverse hypothesis wherein some substance is generating countless numbers of universes like CO2 bubbles in champagne, but with different physical laws and constants, with only those able to continue to expand for billions of years like ours doing so, the rest being failures to launch. Naturally, we awaken to discover ourselves in one of those universes and eventually discover how unlikely it is, but only when considered in isolation, as with a lottery. Whoever wins was unlikely to win when considered in isolation, but when we consider the pool of bettors, the chances that some will win becomes nearly certain.
For example testimonies of people having seen ghost is evidence for ghost and also evidence for hallucinations…………why? because testimonies support both hypothesis
Agreed. And we can order those as well. Hallucination is more likely (more parsimonious), because it doesn't require that ghosts exist. But reason prevents us from guessing, or should. We would all benefit by learning that we can disregard an idea without calling it incorrect until a reason to reconsider it arises.
you said that very likely life came in to being naturally..............I dont grant that premise
The argument is the same: parsimony. We have nature and life, but there is no other evidence for a deity. Here's where your reasoning is fallacious. Nature is evidence for both hypotheses, and though tey can be oredered using the parsimony principle, neither can be ruled in or out at this time, and so we can go no further that to say it's one of those. You've gone further anyway, and just picked one by faith - an intuition, hunch, or guess. Your conclusion is thus non sequitur. It doesn't follow from what preceded it. Had you not taken that last leap of faith, you'd be where I am, which does follow from the evidence.
even if that premise is granted, there is no reason to think that those natural mechanisms and conditions are expected in other planets………….many things have only happened once (like the specific pattern in your fingerprints)
We expect the same laws of physics and chemistry everywhere in the universe, and the same elements.
Regarding your fingerprint analogy, my specific fingerprints are unique, but fingerprints are not. We do not require that the life that arises be identical like an identical fingerprint, just in the same category.
It's a very interesting topic regarding what is necessary for life to form. We can't say for certain, but it seems that liquid water persisting for very long periods of time and containing assorted simple ingredients may be enough, which is why there is interest in looking at the oceans under the icy crusts of Europa and Enceladus. We're still learning.
Maybe that moon or planet needs to be associated with a single star. Maybe binary systems cause irregular orbits that periodically boil that water or causes it to freeze extinguishing whatever life or progress toward life was there. Surface life seems to need the protection that a magnetic field provides, meaning that it needs to have a moving metal core, but life under icy crusts might not. Like I said, we're still learning.
I grant that there is evidence for (and against) intelligent aliens ……..I just don’t think that the balance is on one side…………I would stay within the 50% /50% rage................I just think that the evidence doesn’t support your conclusion of Aliens very likely exist”
By aliens, I mean any life not arising on earth, including single-celled life.
Why wouldn't the existence of life on exoplanets or their moons be expected if it could arise on earth? Physical processes that can occur do occur whenever the circumstances allow. It's not like some of the cups of pure water in a single freezer will freeze and others won't. They'll all freeze together - at the same moment if they're the same volume of pure H2O subjected to the same freezing temperature beginning at the same time, and if the freezer fails and warms up, they all melt together.

It's my opinion that one cannot reason properly if he's using that faculty to try to defend a false or unfalsifiable belief - process which always warps objectivity. That hurt the ID people and caused them to see what they wanted to see but was not there - irreducible complexity. That same observer bias harms clinical trials that depend on subjective assessments by the patient and impartial more objective but still somewhat subjective assessments by the clinician. For that reason, the trial is double blinded, meaning that neither the clinician nor the patient know whether the therapy being tested was administered or placebo.
If you're looking for evidence for a god that you've already decided exists, you'll turn the evidence you find into evidence to support your belief as the ID people did, who saw irreducible complexity repeatedly when none was there. The proper evaluation of any evidence requires a dispassionate, impartial evaluation of that evidence, using valid reasoning only to reach conclusions - just like the arithmetic problem. Vary from that narrow path at all and you're off the reservation. That's difficult to do when you've got a false or unfalsifiable belief directing that process.
