Can Evolution explain a caterpillar turning into a butterfly?
Holometabolos development has been explained fairly simply with modern genetics and the way in which DNA transcription is altered upon the reception of different signals. The selective benefits of holometabolic development should be fairly obvious, in that the adult insects do not have to compete with their larvae for food increasing the survival chances of both. It is not at all limited to just insects however, and in fact this evolved much earlier than you are attempting to make out. There are many organisms that have an entirely different larval form than they do an adult form, such as some sponges (porifera) that have a free living motile larvae that is completely unlike the adult animal (until it settles). The simple rearrangement and differential transcription of certain HOX (developmental hot box genes) genes is the reason for this.
No magic required.

I never thought about how a caterpillar could turn into a butterfly so i'm completely clueless on this subject. But now that you bring it up I would like to know.
The science of Entomology. Romoser and Stoffolano. WCB McGrawHill publishing, 1998. There is a more recent edition of this book out too.
Finally,
www.nature.com has numerous papers describing the evolution and mechanisms involved in insect holometabolic development, although it is normally called complete metamorphosis.

Intelligent Design is an intriguing theory and has several people rooting for it, and it has increasing support in the biology fields, especially in microbiology
Care to tell this microbiologist doing his doctorate where this evidence is? I will accept the PNAS, nature, science, microbiology or any other microbiology paper, because quite frankly this statement is utterly full of rubbish.
Next, name one, just one and ONLY one irreducibly complex system please. Or are we going to dig up the old show ponies, the flagellum which is actually a type III secretion system (hence isn't actually irreducibly complex); the blood clotting system which has now been found to have a simpler one in other mammals that works just as well (again, disproving it as being irreducibly complex); the type III secretion system has now been demonstrated to have a simpler component etc.
Of course, the beauty of using the unintelligent design argument is every time they are proven wrong (and they have on EVERY SINGLE SYSTEM THEY HAVE CLAIMED IS IRREDUCIBLY COMPLEX TO DATE) they just go, oh well we REALLY meant the NEW thing you discovered is actually irreducibly complex. Works wonderfully for guarding their rears, but they clearly have no evidence, and I find it insulting that you would claim my field of science in any way supports these frauds, to support their theory at all.
So as I said, what systems ARE irreducibly complex? So far there hasn't been one and even Michael Behe has admitted things like the flagellum aren't IC, though he now claims the type III secretion system is (and he'd be wrong as has been recently demonstrated).
Creationism is usually looked on as a complete fallacy by the scientific community, if only because of it's "young Earth" component.
There are two kinds of creationism, progressive where God does a series of experiments (destroying a generation of 'failed' experiments on the way) which explains firstly the age of the earth and why there are fossils. Then there are the young earth fellows. Predictably, they don't like each other either.
