How can humans share so much DNA with Lettuce, Banannas and Mushroom’s? Do we share the same ancestors?

Because there’s a lot of DNA that codes for stuff common to all multicellular life. How to build a cell membrane, how to build a nucleus, how to make the proteins that hold everything together, how to make and use ATP, how to transport ions, there is so much stuff that is just like “here are the basic mechanics and parts to run a cell” that are mostly the same.
