Is atheism a scientific perspective?

I think you're right, I'm not understanding the point you are making.

My point is that you are trying to sneak "intention" into the discussion.   Evolution is a mindless algorithm.

Do you think that imperfect replication and differential reproductive success can lead to essentially infinite complexity?

There is no limit to the accumulation of changes.  Complexity is unbounded.

Can it use forward looking memory to select for a sequence that will only lead to functionality 20 base changes down the road?

No, because that is not how it works.  Evolution is a blind, purposeless process.

You assume that there is a gradient of functionality going from none to extremely high with no major jumps.

I have not actually made that claim.  Please define what you mean by functionality.
Overall, evolution is gradual.  If you zoom in on the time scale, there will be 'jumps' - just not often large ones.

I understand that evolution is a mindless process, but I think it is clear that the processes that allow a living system to function exhibit intention. This does not necessarily mean that evolution could not lead to it, but if I was talking about intention, then I'm sure this is how I meant it. 

And I think it is interesting that you actually believe that infinite complexity can arise through evolutionary mechanisms. If you accept that premise, then anything capable of change must be capable of infinite complexity.

We agree that it can't use forward looking memory. Do you deny that forward looking memory was ever necessary? If so, then it seems like you must believe that there is a gradient of functionality (I'll define it simply as accomplishing a specific task) that can be conveyed by DNA sequences changing one base at a time?
