Many people have fallen into believing that Intelligent design is a viable explanation for the way the Universe operates. The clock model, or that it's statistically impossible that all of this should have happened randomly. So everything shows that there was a designer.
OK, but first lets note that if the universe was intelligently designed, then the design must be intelligent. How do you explain the mistakes? Take cancer or diabetes for a moment. How is that intelligent? Genetic theory says that cancers are cells that have stopped working as they are supposed to. We can make more examples of this, but realistically, an intelligently designed system should not have mistakes.
One may reply, there are many items that are designed that would fail that test of intelligence. But we still say that they are intelligently designed. Take the two World Trade towers. They were intelligently designed for their time, but they were not designed to withstand the hit of a fuel packed commercial airliner traveling at over 350 miles per hour.
Yes but that supports the main argument. Those towers fell because of physics and fuel chemistry. They failed not by some random event, but because there was a lack of fire retardant material in the steel columns. c
Intelligent design also assumes that someone knows how the physical laws operates but then extrapolates to requiring a third party ... the leap to designer. Consider Occam's razor. This says that if you have two competing theories that can explain a natural phenomena, then the one with the fewest variables, is the better explanation. Evolution says that the processes of selection, competition, environment, genetics all play a role in the formation of natural and living processes. Intelligent design says that the processes of selection, competition, environment, genetics, and God play a role in the formation of natural and living processes. God is the extra element. Is it needed?
