1. cells are the smallest unit of life
2. cells are the building blocks of life
3. cells come from pre-existing cells
4. cells contain inherited information that controls their activity(this one is mentioned in some books )
I think your statement ,All cells come from other cells, is over simplified,and incomplete.

The Cell Theory Complete
The 3 Basic Components of the Cell Theory were now complete:
1. All organisms are composed of one or more cells. (Schleiden & Schwann)(1838-39)
2. The cell is the basic unit of life in all living things. (Schleiden & Schwann)(1838-39)
3. All cells are produced by the division of preexisting cells. (Virchow)(1858)
Modern Cell Theory
Modern Cell Theory contains 4 statements, in addition to the original Cell Theory:
The cell contains hereditary information(DNA) which is passed on from cell to cell during cell division.
All cells are basically the same in chemical composition and metabolic activities.
All basic chemical & physiological functions are carried out inside the cells.(movement, digestion,etc)
Cell activity depends on the activities of sub-cellular structures within the cell(organelles, nucleus, plasma membrane)
Definition: The Cell Theory is one of the basic principles of Biology. Credit for the formulation of this theory is given to german scientists Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.
Another Definition: The ideas that all living matter consists of cells, cells are the structural and functional units of life, and all cells come from preexisting cells.
Another Definition: (biology) The theory that cells form the fundamental structural and functional units of all living organisms; proposed in 1838 by Matthias Schleiden and by Theodor Schwann
All cells are the result of pre-existing cells
Cells Are the smallest forms of life
All life is composed of cells
Cell is the structural and functional unit of life.
Every living thing is made up of one or more living cells.
Because every living thing is made up of one or more living cells.

Two scientists came up with The Cell Theory. It was in 1839, Matthias Schleidan and Theodor Schwann, two German Biologists came up with this theory.

That would be an exciting discovery to say the least. The theory could be maintained with the condition: Regarding all life native to planet earth... The alien would probably be a really strange creature.
