Why birds do not fall while sleeping

When I was younger, I was fascinated by evolution, especially the intricacies of how things just work. This fascination also explains why many people believe in the intelligent design theory.

However, witnessing the rapid evolution of AI with just a few hundred GPUs, enough data, and power, I no longer wonder what a billion years of feedback loops and randomness can achieve.

Rapid evolution of AI needs a director, a human training and guiding it to get tangible results.

Which is built on all this "billions of years of randomness" to begin with.

Random, that's what we think, bacteria living in gut can also think the whole digestive process to be part of some random universal law

Using your analogy, it's absolutely unknowable to bacteria, and therefore absolutely unknowable to us. Random is perhaps the most intellectually honest way of describing it, since it is widely accepted that randomness is a feature of relatively uncomplicated systems.
