I did not say there was evidence of need. It is you who is making the claim, that being that there is no need for divine manipulation. So burden of proof goes to you.
The evidence that there is
no need for it, is quite simply that the natural process of evolution is sufficient to explain the facts.
When you have an explanation that is sufficient to account for the facts, then there is
no need for any undetectable entities getting involved in unknown mysterious ways.
Like the example I always give of the chocolate cake that goes missing from your kitchen.
Your kids have a stomach ache and their faces, t-shirt and hands are covered in chocolate cake.
The explanation that your kids ate it, is sufficient to account for the missing cake.
Does it rule out that a burglar came into in your kitchen and stole said cake? No.
But it sure shows that there is
no need to invent such to explain the missing cake.
On top of that, you are not even positing something as mundane and known to exist as a burglar. No, you are positing a magical being who intervened in magical ways.........
Since you have left out the "without a designer" but, your answer means nothing. Nobody is questioning whether evolution happened.
The "with a designer" or "without a designer" parts are faith based. BOTH of them are faith based.
Do you require "faith" to not include magical cake thieves to account for the missing cake in the example above?
Also, no possible naturalistic mechanisms eliminate the need for a designer to, for a start, design the whole system
False. The NEED is most definitely eliminated.
If you wish to posit a NEED, then you are going to have to demonstrate that.
A NEED is much stronger wording then a mere OPTION or POSSIBILITY. Even though those would have to be supported with evidence as well, off course.
All you are doing is building a giant argument from willful ignorance. Not just mere ignorance, because we actually know quite a lot about evolution and KNOW that it is sufficient to account for the facts (and thus eliminate the NEED for any other alternatives - magical or otherwise).
and secondly to get each step up and running in situations where nature itself probably could not do it alone.
Which step in particular in evolution would you say that "nature could not do it alone" and demonstrate how you have concluded that.
I'll bet 500 bucks on an argument from ignorance being included in your answer.
