I think it was Ezekial where it talks about Satan (the King of Tyre).
I think you’re correct.. Very few places is there a hint of pre Adam anything..
BTW, the word 'bara' is used in Genesis to specify a completely new thing brought into existence which never was. The word shows up at the advent of the whole universe, at the segment where single cell life transmogrifies into 'multicelluar organisms', and when Adam has the Spirit breathed into him and he becomes a 'living soul'. It will be briefly covered in my coming book, if I ever get it finished.
