Yes, and virtually every scientists will tell you that human beings descended, as did all life, from a single-clled organism in a "primodial soup" based supported by the Miller-Urey experiment that managed to produce only two amino acids and tar!
Your English syntax needs serious help. The theory of common descent, which even (un?) Intelligent Designers admit, posits that all life is descended from single celled organisms. The evidence for Common Descent is overwhelming, regardless of whether or not you're personally incredulous.
Where those first single celled organisms came from is not known at present and is a totally separate question. Some suspect that they evolved from complex organic molecules in a primordial soup, but no firm evidence exists.
