They're both organisms, right?
Cells are the common building blocks of both simple and complex organisms. They are the basic unit of life and are responsible for carrying out all the functions necessary for an organism to survive and thrive.
Complex organisms evolved from simple organisms, so simple organisms evolved first.
My wife is complex. And she's an animal. But I don't think I'd call her an animal to her face...
Complex organisms first evolved around 600 million years ago during the Ediacaran period. These organisms were simple multicellular creatures that eventually led to the more diverse and complex life forms we see today.
Protists are generally single celled organisms grouped under the Protista Family, but recently they have been reconsidered to be a grouping of organisms that have little in common but that they do not fit in elsewhere and while they do have complex organelles, they do not differentiate tissues. They can have various trophic modes, motility, cell coverings, and life cycles.

Simple Organism some simple organisms are made of single cell. Others are made of many cells that are similar Complex organisms in complex organisms, cells are organized into tissues, which make up organs. Organs form organ systems.

Organisms are classified as simple if they only have one cell such as bacteria, and complex organisms have multiple cells that function together to keep the organism alive and maintai homeostasis.

That depends on which organism. Generally, an organism is more complicated than an organ, but if the organism is unicellular (has one cell) then it could be more simple. Since one celled organisms don't have individual organs, then the anwer is that organisms are more complicated than organs.
Simple parts of an organism are basic structures that perform specific functions, while complex parts are made up of multiple simple parts working together to carry out more specialized functions or processes. Simple parts are often found in unicellular organisms, while complex parts are more common in multicellular organisms.
Archaebacteria are some of the oldest organisms living on Earth. They are considered simple because of their external body structure.

Scientists examine the creatures cell structure to see if it is prokaryotic or eukaryotic. Prokaryotic organisms are usually simple organisms and eukaryotic ones are complex. For example, humans are eukaryotic. Bacteria is prokaryotic.
Complex organism generally means multicellular, but in that category there are different levels of complexity. Sponges are multicellular, but don't have distinct tissue, for example. Generally, any living thing that you can see with your naked eye is extremely complex.
