he says that evolution and the Bible can be compatible and so any use of evolution by atheists/skeptics to deny God is unwarranted.
There you go again with that straw man. You really have no interest in why that's wrong or how to make it right, do you? Nor do you seem to mind that I have promised to correct you every time you make it as I will again now. Most atheists neither claim that gods are impossible nor nonexistent, nor do they reject biblical god claims because the conflict with the theory of evolution. Most atheists are agnostic atheists. They reject god claims without asserting that they don't exist - merely that they have no reason to believe they exist even were there no such thing as science, and that they live as if gods don't exist. That's what agnostic atheism is, and it represents the position of most atheists.
You have the same choice again: learn this and stop making this mistake, or demonstrate that you can't or won't and continue to be corrected. You also have the choice to address this now - you never have in the past - or just continue ignoring it like it's never been written.
Garte says that atheist have a rational process to hang their hat on, an intellectual reason, with evolution, to say that there is no God.
And yet again. Are you incapable of conceiving what I've written to you here? It seems so. I don't think you understand the objection, and I don't think you care enough to try to understand, that, or you not only just can't, you might not even be aware that you are being disagreed with, as there's no evidence in your replies that you do.
He claims that science is full of comments by scientists that there is design and mentions Dawkins also who says this but claims it is just an illusion that it looks like design.
I doubt that you've paraphrased Dawkins correctly. And you are committing an equivocation error, conflated the pattern or design in a natural process such as the hexagonally symmetry of a snowflake with the act of an intelligence planning and designing something deliberately. I'm pretty sure that Dawkins is acknowledging that one of these exist in nature but not the other, and that you would like that distinction ignored so that you can imply that even Dawkins thinks the world looks like it needs an intelligent designer.
It is the origins of life through chemical evolution which is not scientifically sound in his opinion.
Why should that matter to anybody else?
the Bible is not intended to be an historical account of the material origins of mankind.
Sure it was. The ancients speculated on how the world they found themselves in god to be the way it is given the assumption of a omnipotent, omniscient creator god that created them and was interested in their behavior. Like all creation mythicists, they were guessing based in limited evidence, and they guessed wrong. The evidence that the biblical mythicists believed them as being historically accurate is in the myths themselves and the commandment to honor the Sabbath just like God did following six days of creation. That's offered as history, as an event that literally occurred in the past.
It is intended to be a mythical representation of the origins of human behavior.
Myths are not representations. Allegories are. Metaphors are. Myths are speculations about what really happened. The origin of human behavior is given in these myths as fact. Adam and Eve chose to disobey because they were made able to and wanting to, and the rest has been a series of smitings and punishments including perdition as the just fruits resulting from an event that occurred somewhere one day. There's no symbolism at all there, just a speculation about how and why the world is as we they found it.
