Is atheism a scientific perspective?

[Whateverist]

So, in a nutshell, talk of "used to accomplish a desired function" doesn't work as function can be attributed to intelligent and natural causes.  It's not a divider.

The first part of your argument seems really shallow. I think you know that we are not saying that "it looks designed therefore it was". It is "despite thorough search for another cause, only intelligence is a known cause that can produce what we see in designed systems". It is not that we are just appealing to our initial intuitions. These conclusions come after careful studying of the systems and proposed explanations. Your argument seems to be "because in the past we have seen apparent design turn out to be illusory, all apparent designs are illusory". 

And the functionality of the wing is the result of elaborate informational output by the cell.  Obviously the wing itself is not information, but I think it is impossible to argue that its functionality is not the result of information. And you say "For if it is even possible that specified information can arise natrually, it's no longer a flag for design." You seem to be suggesting that if it's possible that something arose without design, then it was not designed. This is illogical for several reasons. Also, we have no good reason to assume that it can arise without the help of a designing intelligence. If you have a reason that you think it was can you provide it? You say that abiogenesis is a significant possibility, but I think that's just wishful thinking. We don't have to assign probability to design either, because we know based on repeated experience that intelligence is adequate.

For anything to have been designed by an intelligent being you'd have to produce a being with the means, motive and opportunity.

In the first case you have produced no being, intelligent or otherwise.  Where is this alleged god exactly?  Your hearsay would be inadmissible.

Now the omni qualities you claim your god has might well establish the "means", but those qualities would have to be established too.  Your high appraisal of said god's beneficence might likewise be grounds for the finding of a motive provided He can be deposed.  There is no way to assess opportunity without an opportunity to deposition your god.  

We can't determine that this mysterious being you've defined as omni everything can actually design and produce life based only on the hearsay of a cult that practically worships that being.  Worshipers would have very little credibility.

Sorry.
