Though the questions are not addressed to me, more of my two cents I suppose lol.
Perhaps he could have, but it seems more logical that he manifested Creation within himself, out of himself, in much the same way Jesus, bodily, was manifested in the Virgin Mary by the power of God - the Holy Spirit.
Not incapable, in theological theory, but it might be a bit difficult to understand how God could create Existence out of Non-existence, when he alone is Existence from which existent entities can be made, drawn forth, or made manifest.
There is, the creature is itself by sheer fact of being that creature - in idea, and in its created nature as an image bearer of God. But it is not separate from God, but is (I believe) a manifestation of God, an “exflection” of God.
All evil issues out from the Father of Lies, there is no evil that does not first begin in a lie. A lie that we tell ourself, or a lie we are told by another; such as the Devil or devilish men. Lies do not have any existence, there is no truth in them, they only have seeming existence - like lies - and only really because they are believed and acted upon. This has been my thought concerning the theme of moral evil I’ve seen in the Bible.
Evil is apart from God, it is missing the mark of which He, being Truth, is the standard. Therefore Evil I believe is a lie built upon a lie, believed and acted upon to produce ungodly results - but like lies I do not believe Evil has any actual existence. Evil is a parasite towards the Truth, where truths are twisted or made absent in order to give seeming existence to a lie that does not have it on its own, and therefore must be a parasite. The Devil created lies, but only God can create existent truths and realities.
All activities of people that are evil, are the wills of men willing evil upon the premise of a lie, of a lie, of a lie, stretching back to the first lie ever told to man “in the Garden”. “You will be as gods, knowing good from evil…” but of course, since the Devil is sneaky it was perhaps this in his heart in lying; “you shall be what you think you aren’t, now that I’ve created doubt. You shall be mighty knowing good…and knowing apartness from God…(evil)”
