ID as a scientific theory is laughable and correctly slapped down by the courts.
ID as a ontological belief system seems perfectly reasonable to me. Absent any tangible data, the idea that the cosmos results from a higher organizing principle beyond human cognition is just as likely as the idea that an ordered, mathmatically structured, and finely-tuned universe just popped into existence for no conceiveable reason.
Something had to pop into existence. We can see and measure structures in the universe. They exist. Claiming some spiritual being popped into existence and created it all adds unnecessary complexity with no gain. Why did he pop into existence? Who created him? Why did he create the universe? The universe is a shooting gallery of collisions, explosions, dying planets and stars. it is not well-tuned. Earth will get destroyed by a rock shooting through the universe if we don't blow it up first.
