If the human's body only had one type of cell, they will not be existing. Hence, the answer is no.
The human body is the most complex of all living organisms. It is made up of trillions of cells that are organized into tissues, organs, and organ systems with each organization carrying out different functions. Without these organizations, humans will not be able to carryout essential life processes and as such, not able to survive.
If the trillions of cells are just one type of cell, then, only one tissue, organ, and organ system can be formed. The cells had to differentiate in order for them to be organized into different tissues, organs, and organ systems
In other words, if your body had only one type of cell, the different biological processes being carried out would not be possible and you would not survive.
