No one knows. Some scientists think we arrived here from space on a comet from another planet, witch is really obnoxious. Like, how could the organisms survive the crash? Why would any stupid aliens send they're organisms to another planet? That entire THEORY is stupid. They all go against The Bible and think it's fake. Even though it's the truth! Stupid scientists...they think they know everything.
Edited answer:
Lfe originated as a unicellular organism on this planet millions of years ago and through evolution ramified into various complex multicellular forms of today. Hence single celled organisms contain all the parts of life.

∙ 11y agoLife is something that happens on a biochemical level. It does not require large structures such as arms and lungs, it requires chemical reactions. It can be packed into a very small space. Cells are actually very complicated, and they contain structures called organelles which have specialized functions, much as organs have specialized functions in the body. The information packed into nucleic acids makes life possible.

What organelles are in a single celled organism?
The parts of a single celled organism usually rely on what type of cell it is. A prokaryotehas a nuleouswhile an eukaryote doesn't.
Is rust a single cellled organism?
Rust on your fence or rust on your crops? Rust usually, that occurs on metallic objects is iron oxide, it's an inorganic compound so no cells. Unicellular usually refers to organic organisms of single cellular structure. Another 'Rust' is an organism. Do you mean Rust fungus? It is a fungus and produces spores which spread and cause the crop damage, it's not unicellular. It has a complex structure.
What two things distinguish the organization of most many celled organisms from the organization of one celled organisms?
Hoes and boats
How do the single celled organisms feed?
They ingest food by surrounding and engulfing food ( endocytosis), creating a food vacuole, or eating them trough a small hole on the side of the cell.
Why don't unicellular organisms go through cellular differentiation?
Cellular differentiation is for cells that are to become specialized parts of a larger organism. Think along the lines of brain cells, skin cells, heart, cells, etc. Unicellular organisms are, by definition, a single-celled organism, and that is why they do not go through cellular differentiation.
Why do you say there is no natural death in single-celled organisms?
Single celled organisms do not grow old and die, they are not made of enough parts to "wear out" like us. They simply split into two via mitosis.
What is a single-celled organisms?
Microorganism
What is the difference between living cells that are organisms and living cells are not organisms?
Single celled organisms are examples of living cells that are organisms. Most other living cells are parts of living organisms, but could not survive long on their own.
How does a single celled animal transport substances to all its parts?
single celled animals. GO! GO! GO!
Why do you not have many fossil records from the Precambrian era?
Most life-forms were single-celled, with no hard parts to fossilize.

Which of the single-celled algae are responsible for capturing energy?
The parts of the single-celled algae that are responsible for capturing energy are chloroplasts. Chloroplasts have to be there in order for cells to capture energy.
When an organism of many cells breaks up into two or more parts and these parts survive to produce a new organism reproduction occurs by?
Fragmentation occurs when an organism of many cells breaks into two or more parts and these parts survive to produce a new organism.
