Kwazy Kweationist Deniers say there's "No evidence".
This is one of the best of an Overwhelming body of such.
People get convicted of crimes, including murder, 'beyond a reasonable doubt' on cases that are not as strong as the one for Evo.
Good circumstantial cases are better than eyewitness ones. The latter being the "proof" kweationists goofily demand.
With these Vestiges, DNA, etc, life can traced to a continuum, with many creatures, including us and other MAMMALS, having anatomical vestiges of our evolutionary ancestors.
An 'immaculate' creation event wouldn't leave useless organs/etc.

Prediction 2.1: Anatomical vestiges
[....]Geoffroy was at a loss for why exactly nature "always leaves vestiges of an organ", yet he could not deny his empirical observations. Ten years later, Jean-Baptiste Lamarck (1744-1829) identified several vestigial structures in his Zoological Philosophy.
[....] these "Hypocritical" structures profess something that they do Not do-they clearly appear designed for a certain function which they do Not perform. However, Common Descent provides a scientific explanation for these peculiar structures. Existing species have different structures and perform different functions. If all living organisms descended from a common ancestor, then both functions and structures necessarily have been gained and lost in each lineage during Macroevolutionary history. Therefore, from Common Descent and the constraint of gradualism, we predict that many organisms should retain vestigial structures as structural remnants of lost functions....
Confirmation:
.....For example..independent phylogenetic evidence, snakes are known to be the descendants of four-legged reptiles. Most Pythons (legless snakes) carry Vestigial Pelvises hidden beneath their skin.. The Vestigial pelvis in Pythons is Not attached to vertebrae (as the normal case in most vertebrates), and it simply floats in the abdominal cavity. Some lizards carry rudimentary, Vestigial Legs underneath their skin, undetectable from the outside...Many cave dwelling animals, such as the fish Astyanax mexicanus (Mexican tetra)... are blind yet have rudimentary, Vestigial eyes....
[....]
The ancestors of Humans are known to have been Herbivorous, and molar teeth are required for chewing and grinding plant material. Over 90% of all adult humans develop third molars (otherwise known as Wisdom Teeth).
Usually these teeth never erupt from the gums, and in one Third of all individuals they are Malformed and Impacted. These Useless teeth can cause significant pain, increased risk for injury, and may result in illness and even death.
Another Vestige of our Herbivorous ancestry is the vermiform appendix. While this intestinal structure may retain a function of some sort, perhaps in the development of the immune system, it is a rudimentary version of the much larger caecum that is essential for digestion of plants in other mammals..."
Yet another human Vestigial structure is the Coccyx, the four fused caudal vertebrae found at the base of the spine, exactly where most mammals and many other primates have external Tails protruding from the back. Humans and other apes are some of the only vertebrates that lack an external tail as an adult. The coccyx is a developmental Remnant of the embryonic tail that forms in humans and then is degraded and eaten by our immune system ... Our internal tail is Unnecessary for sitting, walking, and elimination (all of which are functions attributed to the coccyx by many anti-evolutionists). The caudal vertebrae of the coccyx can cause extreme and unnecessary chronic pain in some unfortunate people, a condition called coccydynia. The entire coccyx can be surgically removed without any ill effects..
