The type of cellular organism that likely existed first on Earth would've been the prokaryotic cell, because it is the simplest form of like known to man.
As far as we know, the steps of the formation of life on Earth went like this (from longest time ago to most recent):
Prokaryotic cells, eukaryotic cells, sexual reproduction, multi-cellular life
It's also important to note that the Earth is over 4 billion years old, so all of these processes have been going on for a long time.
