The microscope allowed scientists to observe cells for the first time, leading to the discovery of their structure and function. This observation of cells led to the development of the cell theory, which stated that all living organisms are composed of cells, cells are the basic unit of life, and all cells come from pre-existing cells.
Theodor Schwann discovered that all animals are made of cells. He recognized nuclear structures similar to what Schlerden (another scientist) observed in plants. He extended that cell theory to animals, stating that all living things are composed of cells.
Theodor Schwann, a German physiologist, was the first scientist to determine that all plants, as well as animals, are composed of cells. This discovery was made in the early 19th century and formed part of the cell theory that revolutionized biology.
Scientists who have made significant contributions to the study of cells include Robert Hooke, who first observed cells under a microscope in the 17th century; Matthias Schleiden, who proposed that all plants are composed of cells in the 19th century; and Theodor Schwann, who extended this idea to animals, formulating the cell theory.
In 1838, German botanist Matthias Schieiden concluded that all plants came from cells.
Theioder Schwan stated it first. He contributed to cell theory

The first place to look is at the cellular level of organization. Plant cells will have cell walls composed of cellulose as well as a plasma membrane; animal cells do not have cell walls.

Robert Hooke- saw dead cells of a piece of cork under a microscope. He named them cells because they looked like tiny rooms which means "cells" Anton van Leeuwenhoek- first to see living cells under a microscope. Theodore Schwann- said that all animals are composed of cells. Matthias Schleiden- said that all plants are composed of cells. Rudolf Virchow- said that all cells come from preexisting cells. (cell reproduction)
1) Matthias Jakob Schleiden- he stated that the different parts of a plant organism are composed of cells2) Theodor Schwann- he stated that all living things are composed of cells3) Rudolf Virchow- He explained that cells divided and new cells are formed from pre-existing cells.4) Robert Brown- named the cell nucleus5) Felix Dujardin- the first to state that cells were not hollow and described about the jellylike material in animal cells and termed it as sarcode6) Henri Dutrochet- proposed that new cells arise from within old ones7) Robert Hooke- first described cells in 1665.8) Antony van Leeuwenhoek- published his observations of single-cell organisms, or "little animalcules" as he called them.9) Henri Edwards- suggested that the basic structure of all animal tissues was an array of "globules,":DD
1665 Robert Hooke examined cork under a microscope and described "a great many little boxes" that reminded him of the cubicles or "cells" where monks live. He coined the phrase "cell". 1674 Anton van Leeuwenhoek - First to observe and report living cells. First to see and describe bacteria. 1838 Matthias Schleiden - First to observe and report that all plants were composed of cells. 1839 Theodore Schwann - First to observe and report that all animals were composed of cells. Theodore Schwann and Schleiden are attributed to the first two points of the Cell Theory. 1855 Rudolf Virchow - He finished the Cell Theory with the Latin phrase "omnis cellula a cellula" which translated means "all cells arise from cells"

Nobody has the exact answer to how mankind began. It is thought that the first living cells came about due to the combination of enzymes in the sea or from a meteorite falling to earth. Eventually humans evolved from these cells and animals.
