Whatever,
The ightheosaur (? spelling) is a reptile that swims, yet its shape was similar to the dolphin, yet its obvious they are two different kinds of creatures, the bat that flys has a totally different wing than has a bird, but these cladistic similarities only show its a common creator, the dragonfly wing is totally a different design, though having a wing doesn't suggest a common ancestor, but a common creator.
What you are describing are homoplastic characters. Cladistics is able to tell this because cladistics will infer the most parsimonious cladogram with insects, bats, & birds in separate clades, same with whales, ichthyosaurs, & fish. This means the characters arose separately, rather than by dint of common descent.
How does this show positively common creation?
Your argument seems to rest on the assumption that wings etc (that are morphologically distinct in any case) cannot evolve more than once.
