What do you mean by “in the past”? I suppose you must mean in the past of our universe, because you’re talking about “past” as a point in time, and created time is relative to our universe. Outside of our universe is eternity. There might be other “pasts” and “futures” of other universes that don’t have any connection to our own.
Our time, “past” and “future” probably have nothing to do with the “times” (or lack thereof) of any other universes or completely different forms of reality or nature God might choose to create elsewhere.
God probably, in my opinion, has created other “worlds” and “universes,” if those words are applicable, aside from our own universe. Other forms of reality and/or life, anyway. I don’t know whether such ideas as what reality or life was created first has any meaning, though, in view of God’s eternal character. In this universe, though, have there been other worlds and forms of life created? Well, new insect species on Earth are discovered every day, and if evolution is true, the Earth has looked completely different, been a different “world” many times over already. If that’s true here, why not elsewhere?
It may be that the whole universe was made for us, though, and for no one else. Or maybe it was all made for us, and all for the angels, and all for other species on other planets, and we were all made for each other as well. I don’t know. Christ did become human, though, not an angel and not any other species. We are made in the image of God and He came in our image. The awesome power of the Incarnation is central to the fulfillment of the whole universe’s destiny, including any other species, worlds or times. The divinization of humanity in Christ is astonishing, and St. Paul writes that the whole of creation is groaning in its wait for the sons of God to be revealed. This leads me to believe that in this universe, God’s greatest purposes are for the human race, for they shall be made into the Bride of Christ, and to which of the angels did He ever say such a thing? The angels are friends of the Bride and the Bridegroom, majestic servants to both who are greater than us by power and by nature but shall be ruled by the saints when Scripture’s prophecies are fulfilled.
In this universe, there may indeed be other intelligent races like the angels, and other worlds that they live in, but I think that they must all look on humanity with awe because of the Incarnation of Christ. In this universe, humanity is what has become worst, and humanity is what shall become greatest, that the glory of God might be most perfectly revealed to all and in all.
I agree with this, definitely.
