It all began like 5 million years ago, from just one cell. This cell then merged with other communities to a multicellular being, and the same evolution continued till the formation of the apes. Then Natural selection (Adaption of an organism in his environment to survive) continued this evolution over million years, till the apparition of the Homo Sapiens, or as known today, the Humans.
