Maybe it would help with understanding but I don't think that it's necessary to know who the designer is in order to be able to identify design.It should give us reason to look for the designer but still first things first - are we alone or is a designer responsible for all the amazing creatures that do exist?
But once you've identified the design what can be done to understand the design without knowing who the designer was? When asked a simple question about the different methods of reproduction your only reply was 'Design?' , so what more can we infer about why those specific designs were chosen?
As for who the designer(s) is you must have some ideas, since you accept that things are 'designed'. However, you admit that the designer(s) is basically incomprehensible. Can you even guess if they are supernatural in origin or simply very advanced aliens?
This is why the hypothesis of a designer or designers is completely useless to science, since there is no possibility to further our understanding of the universe, since as you admit, we can't comprehend the designer, so we can't understand their design choices. In other words there is no how, and we can't ask why. Unless there is some other procedure we can follow. Any suggestions?
