God created the plants, but then he realized he needs the animals to treat the

Good thing for us that they did oxygenate the biosphere :)
There are quite a few anaerobic microbes that have a very low tolerance for
oxygen, but thrive in anoxic environments -- I had always assumed that these
lineages go back to before the cyanobacteria. Maybe I am mistaken though. Not
sure.
