I do not share your understanding of Satan, the tree of the knowledge of good and evil, different ages, etc. but I would like to address your question here:
God alone sees all that there is all at once, every where and every when. Everything was made by Him for for Him, i.e. all things are factually His to do with as He pleases:
The earth is the LORD'S, and the fulness thereof; the world, and they that dwell therein. - Psalms 24:1
For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: - Col 1:16
Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die. – Ezekiel 18:4
Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour? What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction: And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory, - Romans 9:21-23
At the pace things are moving in this world it won't be long to know which prophecies are unfolding.
I do not share your understanding of Satan, the tree of the knowledge of good and evil, different ages, etc. but I would like to address your question here:
Hebrews 2:14 Forasmuch then as the children are partakers of flesh and blood, He also Himself likewise took part of the same; that through death He might destroy him that had the power of death, that is, the devil:
It is most difficult to respond to a blanket statement of disagreeing with me, and giving no indication as to what the Words of God are instructing. I just can't ignore what is Written, most especially when Christ Himself declared as Written in Mark 13:23 But take ye heed: behold, I have foretold you all things.
Granted He did not declare any or all the peoples to the end of this world would hear and see with understanding what this warning encompasses. But the answers must need be included given this declaration.
It does not make sense that God would claim ownership of something/someone that did not already exist?
Time, including the arrow of time (past>present>future), does not apply to God. Time is part of the Creation and not a property of, or restriction on, God the Creator of it. God alone sees all that there is all at once, every where and every when. Everything was made by Him for for Him, i.e. all things are factually His to do with as He pleases:
I do not understand how Peter's instruction on how God keeps time is a restriction on God the Creator. Especially when up until the flood those people lived nearly one day with the Lord. Genesis 6, God changed the amount of time He would allow a flesh body to live because of the fallen angels or as they are called sons of God.
Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created. – Revelation 4:11 The earth is the LORD'S, and the fulness thereof; the world, and they that dwell therein. - Psalms 24:1 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: - Col 1:16 Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die. – Ezekiel 18:4 Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour? What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction: And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory, - Romans 9:21-23 Jesus being called “the Lamb slain from the foundation of the world” is an example of the arrow of time not applying to God: And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. – Revelation 13:8 So also is the Book of Life: The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is. – Revelation 17:8 And again: According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: - Ephesians 1:4 God's Name is I AM.
This word 'foundation' is a time signature. The word foundation used in the Scriptures cited as well as other places is katabole a noun, and the verb kataballo.

I just did an internet search for the word katabole and the above is but one link that gives discussion upon this particular Greek word(s). Other than that I have no association with this particular link. However, I do use the Strong's so I can look for myself the original word used to find the meaning. Some words from the original can have more than one meaning and depending upon which word the translators picked can flavor a verse away from the intent. The most egregious example is where somebody used the word Easter in place of Passover. My fingers are stiff and sore so I am attempting to type as little as I possibly can.
I would point out in the Revelation 13:8 IF the meaning 'casting down / overthrow' are used instead of the word 'foundation' then the verse would read
And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain, from the casting down/overthrow of the world.
And this 'him' that the whole world (except the elect) will worship is the same entity that tempted Christ, and he will be calling himself Christ.
This casting down/overthrow translated 'foundation' point to Genesis 1:2.
