Why is it said we have all evolved from a single cell?

when the earth was first formed, there was no life on it.its surface was boiling hot,and had giant volcanoes that threw fiery rocks,dust,and gases into the air.
The form of life was an organism consisting of only one single cell.these single celled organisms developed into multi cellular organisms that first plants, and then animals,evolved. so we can say that we have all evolved from a single cell!
