This is a fossil of a Tyrannosaurus rex. This is evidence that this creature existed in the world but because it is now fossilised normally means that all of it's species is now exstinct.

In this image we have some raindrops attached to the branch of a tree. This is evidence that it was raining previously and it was still wet after.

This is Evidence of a crime. There is dried up blood with a bullet casing stuck in it. This is evidence that someone was shot and that they started to bleed.

This is a scar, This is evidence of a previous injury on someones face, this scar can be evidence that it was an accident or it could be evidence for a knife crime, judging from how deep it is and long my guess would be the latter.
