Everything that they studied that had cells was alive,
everything without them was not.
Scientists find evidence in fossils and living things such as changes in morphology, genetic similarities, and transitional forms that support the theory of evolution. Fossils can show physical adaptations over time, and living organisms can reflect common ancestry through shared genetic traits. These pieces of evidence help scientists to understand the evolutionary history and relationships between different species.
Scientists use various lines of evidence, such as the fossil record, comparative anatomy, embryology, and genetics, to show that living things have changed over time. By studying these pieces of evidence, scientists can construct evolutionary relationships and track changes in species over generations. This accumulation of evidence supports the theory of evolution.
While plants are considered living things, there is no evidence that they are conscious.
Scientists/experts that classified them as non living things.

As of now, there is no confirmed evidence of living things in outer space aside from Earth. Scientists continue to explore space for signs of extraterrestrial life, such as microbial organisms on other planets or moons.
they help living beings by biology
They are taxonomists.

Scientists classify living things because then it's easier to share information, study, & discuss these living things.
Scientists use various methods to determine if living things are related, such as comparing similarities in DNA sequences, anatomical structures, and embryonic development. These similarities suggest a common ancestry and evolutionary relationship between organisms. Additionally, the fossil record and biogeographical distribution of species also provide evidence for relatedness among living organisms.
Yes.
