One of the aspects that we often ignore in these discussions is intent and motivation. What was the intent of the designer? What was the designer's motivation for producing that design?
Early stone tools might be a good example to use. Scientists argue back and forth about whether certain rocks are simply rocks, or if they were purposefully shaped as tools. One of the important aspects is determing what the design was intended for. If they think the intent is to use a rock as a cutting tool for plants, then they can look at specific faces to look for parallel striations that would indicate constant cutting in one direction.
If we start with the premises that life is designed (i.e. species designed separately and did not evolve), then we could only conclude that part of the intent and motivation of this design process was to fool us into thinking that life evolved. There are literally billions of different ways to design functioning species that would not look like evolution, so why, out of all of the billions of possibilities, would a designer choose the one way that would look like evolution? Obviously, the motivation was to fool us.
