Let’s imagine trying to design something as “simple” as a self-replicating cardboard box.
“Imagine engineers were able to design cars with car building factories inside, with the ability to build new cars with car building factories inside them.”
Here is a modest attempt to summarize the main scientific evidences for design in our world, for those who have been told that such evidence does not exist.
Conditions on Earth, the laws of physics, are not only fine-tuned for the survival of intelligent beings, they are fine-tuned for the development of technology.
If engineers could make something like a seed, it would be absolutely phenomenal. Then, imagine getting the object to last for thousands of years and still work.
