Why does every one have cells

Everyone has cells because these are the building blocks of life. These tiny particles that clump into groups that form tissues, organs, and organ systems are what makes organisms distinct from non-living things that exist on Earth. Where there are cells, life is present, and in its absence life cannot exist as we know of today. Cells are responsible for bringing different species of organisms that are found in different ecosystems all over Earth. They are tiny but in groups they are responsible for every living organisms that have existed through time.
