You need so many cells, billions and billions, because as a human you are an extremely complex organism. If you think about all the different organs in your body, such as your brain, heart, liver, intestines, stomach, pancreas, etc..., you see that there are many different types of cells needed to compose these things.
Also, since cells are microscopic and can't just keep growing forever, if they did we would have a DNA overload, as we grow we must add new cells to our body.

it has more human cells actually the human body has more bacterial cells. Although it may seem more likely that the human body would have more human cells than bacterial cells. -Vasillisa
There are many uni-cellular organisms which are single celled and survive independently without depending on other cells. If your question is Can a Human cell survive out of Human body? Yes, the human cells can survive out of human body if all the nutrition and the other factors which keep the cell to function are provided to the cell. multi-cellular organisms are made up of tissues of different kinds and organs which are inter-dependent for nutrition and survival. So if the cells are removed from human body, it will survive till the nutrition gets exhausted. There are many scientific methods by which the nutrition and other required substances are provided to the cells which are taken from human body and stored for long periods. The cells are also made to multiply outside the body and it is known as cell-culture or tissue culture.
The average human body consists of approximately 100,000 billion cells.
Human somatic cells typically have 46 chromosomes.
Unspecialized human cells are typically referred to as stem cells. These cells have the potential to develop into different types of cells in the body.
Dead brain cells can't multiply.
Adult stem cells are undifferentiated cells, found throughout the body after development that multiply by cell division to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells, they can be found in juvenile as well as adult animals and human bodies.
Skin cells use mitosis to multiply. Only sex cells use meiosis to multiply.
Adult stem cells are undifferentiated cells, found throughout the body after development that multiply by cell division to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells, they can be found in juvenile as well as adult animals and human bodies. Creative Bioarray provides adult stem cells from various tissue/organs of human, mouse and rat.
Cells double themselves.
Cells multiply by dividing ( which is an oxymoron) is done by the process called Mitosis.

cells multiply by dividing them
No. The cells must undergo mitosis and multiply themselves in order for any organism to grow. The size of the cell does not change. Only the quantity of them do.
If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3If you had the two cells A2 and A3 and wanted to multiply them, then the simplest formula is:=A2*A3
