Why. When I draw a picture or sculpt someone, I don't need a rhyme or reason. I do what the heck takes my fancy to do. I don't sit back and worry myself about being subjected to an inquisition by you. Why should God have done so. Did he have something to fear from your disapproval of how he did things. Again, awful presumptuous. Has it ocurred to you that the way Bats hang upside down in wet caves and hold their young might present problems if Bats had feathered wings. Bats don't act or function like birds. And if efficiency of design is such a no brainer and Lamborghinis are the best car on the road.. why aren't semi trucks shaped like Lamborghinis. Oh, that isn't fair is it. screwing with the design of something obviously meant to serve a different purpose and operate differently. The design makes sense for the purpose of the critter. But who knows - if I can see that - perhaps a mighty being capable of speaking the sun into existance can also design a bat to function properly.. Might be assuming too much for someone whos ways are much higher and more complex than ours.
No. Because there are plenty of birds that live in wet environments and raise their young perfectly well with feathered wings.

Your analogy fails. Birds and Bats aren't like trucks and lamborghinis. They're more like ferraris and lamborghinis: they occupy very similar niches and do very similar things. If you were designing a sports car, would you ditch all of the things we know about lamborghinis, ferraris and corvettes and start from scratch? That is, to a large extent, what has happened with bats when compared to birds.
The design makes sense for the purpose of the critter.
I didn't say bats don't make sense, I'm just pointing out that it doesn't make sense to take everything that works on birds and then try to re-invent it.
