I found a pair of excellent arguments against Intelligent Design: here and here
Here’s my favorite of the two:
A newer, alternative view provides balance to the age-old argument, pitting creationism against evolution. It’s called intelligent design. It studies the science of intelligence or intelligent life.
This his simply a lie, and I thought Christians were not allowed to lie. Intelligent Design doesn’t study anything, ID has postulated a set of theories that are beyond study and therefore not scientific, even if, by an astonishing miracle ID was a correct description of the world, it would be wrong to teach it in science class.
Intelligent design can and has been proved scientifically.
This is another lie, the Christian is really going at it today. ID has never been tested simply because it is not testable. Also, the sentence above shows with utter clarity why you are so amazingly wrong, you are just ignorant. Science, outside of a rather narrow field, doesn’t deal with proving things much, it deals with falsifying things, and the difference is enormous.
Intelligence leaves behind a characteristic signature.
This could probably said to be true, close to the first true sentence in your posting. There is a huge problem with it though, there is no characteristic signature in life that would imply intelligent design.
I propose the followers if the ID ideology change the name of it to BSD. The Theory of Bloody Stupid Design. You see, in all the life we see around us there is evidence after evidence of a Bloody Stupid Designer, if you look. A few examples:
- Why is mankind created with a spine that is perfectly designed for waking on all fours when we walk on two? In fact, the spine is designed so horribly badly for bi-pedal movement that any engineering student could do significantly better after the first 6 months in engineering school.
- What kind of idiot would design a sea-living mammal like the whale, with the remnants of legs inside its lower abdomen? What on earth would a whale do with legs in it’s abdomen?
- The human pain system is designed in a marvellously stupid way. If I suffer from a small amount of tooth decay, I suffer significant pain, this in spite of the fact that the tooth decay is not at all dangerous to my life. On the other hand, if I get a cancerous growth in my lungs, I notice nothing until it is too late to save my life. What kind of moron would design a warning system like that?
- Several parts of my internal organs, the appendix being a notable one, is designed in such a way that inflammation, and until quite recently - death, follows. This in spite of the fact that the dumb thing serves no purpose whatsoever! Would you praise GM for having a nonsensical device in your car that blows your engine to pieces if it rains for three days in a row?
- The eye is a fantastically complex mechanism, but it has a design flaw, very minor, but the design flaw reduces the accuracy of the eye with as much as 50%. Why on earth would you be dumb enough to do that in humans? The design flaw would be trivial to fix if you designed a human from scratch.
- A bi-pedaled entity like the human would be able to walk faster, suffer less back pain and in general be far healtier if our knees were jointed the opposite way of the way they are. What kind of moron would give us knees that work great if you walk on all four, but not so well when you walk on two?
The list goes on and on. There is no trace of any intelligence whatsoever in our design, but there is a lot of traces of random changes, adaptation of body-parts to jobs they are not particularly well suited for etc. If there was someone behind the design of humans, he would fail Human Design 101. Bloody Stupid Johnson.
