Interesting. I remember our pastor way back in 69 preaching about space. He conjectured that yes there were humans on other worlds light years distant, but they had never fallen from grace. In that respect we alone were “special”.
As I recall, scripture states that the entire CREATION has been groaning ever since the fall of man and all is anxiouslly waiting, groaning until the sons of God are revealed at the last. I reckon it’s all part of the total creation.
