No edit undo?!?!

Why is there no ‘un-do’ button?! this frustrates and annoys the absolute hell out of me and I literally just purchsed this about 20 minutes ago. The first selection I made was erased and blended perfectly fine. The second object I selected and erased did not come out the same at all. The cloning tool only did so much to help fix and blend what was left from erasing the object. And of course because there’s no ‘un-do’ I had to completely start over.
