Yes, he did. "For we know that the whole creation groans and suffers the pains of childbirth together until now.

Tell me what that tells you about "out there". It seems totally irrelevant to the discussion. Flesh out its relevancy for me.

If the whole of creation is cursed, then positing aliens not descended from Adam and Eve are in the creation is to suppose that they are subject to (and suffering from) the Curse, despite not sharing in our sin nature. This leaves open the possibility of non-sentient biology, but would seem to rule out sentient ET life.

There is also the question of the centrality of man in His creation (Hebrews 2:7, 9, Psalms 8 and so forth), and that God became man to undo the Curse on all creation. These passages would be inconsistent with a notion that we are one sentient species among many of equal status.
