You are positing nothing and I am positing a being who has shown Himself in history according to many people.
King Arthur and Hercules showed themselves in history according to many people. Hearsay and folklore aren't evidence.
Evidence for evolution does not point to "no designer", that is a faith based position.
That is an easily observed, reproducible mechanism. There's no faith involved.
You are being confused now. It is not me who first came up with the idea of "need". It is atheist who say there is "no need",,,,,,,,,,,, and using your idea, that would be stronger than saying there is no OPTION or POSSIBILITY. Are you saying that there is no "option" or "possibility" of a designer? That is a strong statement and is a statement of faith.
No. Given that natural selection works automatically with no planning needed, no added "causes" are needed. Evolution is not based on faith, and your "designer" is an unneeded special pleading.
Actually I would say that it is you who has the argument from ignorance. You are saying that there is lack of evidence for a designer so that means there is no designer.
No. Lack of evidence means the possibility is at the same confidence level as graviton pixies or transdimentional beavers.
Reasonably, things are not considered just because they are possible. There would be endless possibilities to consider. Unless there's either evidence or need for an extra factor, none is even reasonably considered.
And let's not forget that you are willfully ignoring the idea that this designer could be spirit, uncreated, not a detectable part of the universe.
So he's be indistinguishable from a nonexistent designer....
Why this desperate need to invent completely unevidenced, extraneous 'causes'? The invisible designer could just as well be the Flying Spaghetti Monster.
And let's not forget the fact that you and science do not know if a designer changed the environments for the system to work or initially designed the whole evolution system.
Science acknowledges this but you have a position of faith, a belief that there is no designer and go beyond what science says, even if you pretend to be the one who is on the side of science.
You're inventing scenarios out of whole cloth, completely unevidenced.
A conclusion of non-existence in the absence of evidence is not a position of faith. It's the default position of reason.
No, I just believe that there is a designer. I am not arguing that there is definitely a designer.
You claim there is no need, so demonstrate how you conclude that if you want or just stick to your position of faith, that there is no designer.
We've explained it a dozen times. If there's a well-evidenced, sufficient mechanism already existing, there's no need to invent extra mechanisms -- or agents. An extra mechanism, especially an unevidenced one, is simply not needed. It's a special pleading.
Arguments from ignorance are probably common with people who are arguing that God definitely is needed or definitely is not needed.
I have faith that God did it, you have faith that there is no need for a God, but seem to want to make it something that only I need to justify by argument and that you do not. But if you are the one making the positive claim, that there is no need for a designer, then you should show it to be true.
The positive claim is demonstrated by the alternative sufficient cause.
Your faith, ie: unwarranted unevidenced, and unneeded belief in magic, is epistemically worthless.
