Fossilised ancient life-forms. There are even fossilsed bacteria from 30 billion years ago.
It's called a FOSSIL.

evidence
Naturally. Carbon atoms are present in everything that are organic or are organic derivatives. In any substance obtained from plants or animals, carbon atoms are naturally present.
No
The evidence was circumstantial and not enough to prove any guilt.

Fossils can be made of any material that deteriorates slower than the sediment that forms the fossil hardens

half-life
At this time we have no evidence of any extraterrestrial life.
There is no such evidence. While it seems likely that, given that life appeared on Earth, it may also have appeared elsewhere, there is no actual evidence that makes it even likely that life DID appear in any specific place.
It is any trace of an ancient organism that has been preserved in rock.Fossils provided evidence for continental drift by Wegener's hypothesis. Wegener studied land features, fossils, and evidence of climate change.
