not a single atheist has ever shown a god does not exist.
Nor need he to reject the claims of theists that a god does exist. We also don't need to show that vampires and leprechauns don't exist to reject claims that they do. Many people need a good reason to believe something, without which, they don't. Others need nothing more than the will to believe, and so they do. No theist has ever shown that a god DOES exist, but that doesn't matter to them, does it?
Surely there are people who believe that vampires exist. They would make the same arguments that theists make mutatis mutandis: "Not a single avampirist has ever shown that vampires don't exist." Assuming that you don't believe in vampires, how would you address that argument?
I don't know what ideas you assert about creationist websites.
They're dishonest. They exist to make specious arguments against evolutionary theory (and any other science that contradicts their faith-based beliefs), which can only serve one of two purposes - to deceive the gullible into becoming creationists and to make creationists feel like they and their beliefs are on an equal footing with scientists and science. The mistake creationists make is bringing those apologetics to venues like this one, which contains the scientifically literate. That's counterproductive to the purpose for which they were created. As you know very well by now, they can't change the minds of critical thinkers, who point out the errors and fallacies.
Are you unaware that your posting makes your position less sound and only serves to reaffirm to the scientifically literate that they are correct and that you are not? That's why I have asked a few times why you do this. Do you think that it helps your case for other posters to see that the people who agree that evolution occurred are well-read on the subject while those that reject it can't get the basics right?
Remember, the purpose of the apologetics is to make your position seem to be based in reason applied to evidence. For that to work, you need an audience that might or will believe you, one incapable of seeing the flaws in the apologetics. You need people that think that if something wasn't observed, it didn't happen. You need people who think that if there is still work to be done delineating pathways, that the theory is false. You need people who are willing to apply double standards to the science that they don't apply to their own beliefs.
But you don't have that here. What you have is a panel people telling why the apologetics is wrong. I shake my head in wonderment as to why you would do that. Are you unaware of the effect your posting has? Or maybe unconcerned?
There is no ... evidence showing the actual gradual changes from whatever fish supposedly moved on by natural selection or survival of the fittest to eventually morph to be humans.
But there is. There's just none for YOU and others that refuse to learn or are incapable of learning from it, but that's by choice. You choose to see no evidence, so you don't see any. There's no mystery there including why you would do that. The mystery to me is why you come to this site to make these arguments.
There has been no evidence of seeing any fish develop legs and plodding on to ground them developing lungs by mutation etc.
We don't need to see it to know that it happened. Nobody saw you evolve from a zygote to a fetus, but we both know it happened. Ask yourself how we know that even if nobody witnessed it.
