Why do mRNA vaccines use mRNA in order for the body to create the covid spike protein? Why can't we just create the spike protein and make a vaccine using that (eliminating the intermediate step)?

Since a single copy of mRNA produce many copies of the spike protein, it’s easier and more efficient to have your body produce the spike protein without having to worry about stability of the spike protein in solution, the spike protein forming aggregates, etc. it’s just much cleaner to inject the stabilized mRNA and let your body take care of the rest.
