The arguments are used in the Bible against gods, rather than God. That is, everyone having their own little polytheistic pantheon that looks just like them and have arms and legs and shit. I guess this approach decrying gods that can be represented and have determinate form is called Iconoclasm. So: most atheist arguments are iconoclastic arguments lifted from the bible and adapted.
