If you disbelieve in God, merely look at the beauty of humans.
There is an oblique grand design behind humanity.
On a wide spectrum of looks, the entire idea of what a human looks like is fulfilled. An average human is a decent looking creature, while a subaverage human is a strange and subtle design. Above average humans have faces in which emotions are much more greatly expressed and appear as a great work of aesthetic artistry.

In comparison to the animals, the faces of people are much more distinct, generally being almost entirely unique.
The morphological difference between a frog and its ancestors and a human with their ancestors separated by a million years is starkly contrasted.
We are clearly a cut above the normal products of evolution.
