Cell Membranes, origins through natural mechanisms, or design ?

According to this website : The Interdependency of Lipid Membranes and Membrane Proteins
The cell membrane contains various types of proteins, including ion channel proteins, proton pumps, G proteins, and enzymes. These membrane proteins function cooperatively to allow ions to penetrate the lipid bilayer. The interdependency of lipid membranes and membrane proteins suggests that lipid bilayers and membrane proteins co-evolved together with membrane bioenergetics.
The nonsense of this assertion is evident. How could the membrane proteins co-evolve, if they had to be manufactured in the machinery , protected by the cell membrane ?

The ER and Golgi apparatus together constitute the endomembrane compartment in the cytoplasm of eukaryotic cells. The endomembrane compartment is a major site of lipid synthesis, and the ER is where not only lipids are synthesized, but membrane-bound proteins and secretory proteins are also made.
So in order to make cell membranes, the Endoplasmic Recticulum is required. But also the Golgi Apparatus, the peroxysome, and the mitochondria. But these only function, if protected and encapsulated in the cell membrane. What came first, the cell membrane, or the endoplasmic recticulum ? This is one of many other catch22 situations in the cell, which indicate that the cell could not emerge in a stepwise gradual manner, as proponents of natural mechanisms want to make us believe.
Not only is the cell membrane intricate and complex (and certainly not random), but it has tuning parameters such as the degree to which the phospholipid tails are saturated. It is another example of a sophisticated biological design about which evolutionists can only speculate. Random mutations must have luckily assembled molecular mechanisms which sense environmental challenges and respond to them by altering the phospholipid population in the membrane in just the right way. Such designs are tremendously helpful so of course they would have been preserved by natural selection. It is yet another example of how silly evolutionary theory is in light of scientific facts.
