A fossil. Fossils are the preserved remains, impressions, or traces of ancient organisms that provide evidence of past life on Earth. They can include skeletons, shells, footprints, and more.
Yes, there is scientific evidence to support the theory that Neanderthals interbred with early humans in ancient times. DNA analysis has shown that modern humans outside of Africa have Neanderthal DNA in their genetic makeup, indicating interbreeding between the two groups.
Fossil records, anatomical similarities, embryological development, and genetic similarities are all forms of evidence that support the theory of evolution. These pieces of evidence show the gradual changes in species over time and provide support for the idea that all organisms are related through common ancestry.
Living things are called organisms. Organisms are any individual entities that exhibit characteristics of life, such as growth, reproduction, and response to stimuli.
There is no scientific evidence to suggest that birds can be sexually attracted to humans.
Fossilised ancient life-forms. There are even fossilsed bacteria from 30 billion years ago.
The remains of any previous living object is called "fossil." Fossils can be bones, shells, imprints, or any other preserved evidence of ancient life.
Any evidence of ancient life is called a fossil.

A fossil is any evidence of ancient life as recorded in rock, including feces, teeth, digestive stones, nests, eggs, bones, tracks, and burrows. ~ fossils provide evidence of the activities of ancient organisms.
A fossil is any evidence of an organism preserved in rock.
Fossils can be made of any material that deteriorates slower than the sediment that forms the fossil hardens

At this time we have no evidence of any extraterrestrial life.
Life forms from Venus would be called Venusians. Life forms from Mars would be called Martians. In any respect, however, there is no evidence, nor scientific support of life on either Venus or Mars.
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.
Some types of evidence of ancient life that can be preserved as fossils include bones, teeth, shells, footprints or trackways, and imprints of soft tissues. Plant material such as leaves, wood, and pollen can also be fossilized.
