It might have been said by someone profoundly ignorant of biology. The cell membrane is a very simple structure:
These bilayers spontaneously form vesicles, which hold the contents of the cell. The "random" part is also evidence of ignorance. Cells could not have evolved randomly. But then natural selection isn't random.
Perhaps. God says the Earth brought forth life. Science is just now understanding how that might have happened. But the fact that the one indispensible part of cellular life is the simplest structure in the cell does make it seem more likely.
