Short answer: no. The Bible never directly mentions aliens or life on other planets. It doesn’t rule them out either, though.
I’ve lost more late nights to this rabbit hole than I care to admit. Some folks point to Psalm 19 and the ‘heavens declaring the glory of God,’ but that passage is about creation praising its Creator, not aliens (see this thread).
Deciding the question doesn’t threaten anything. If God made life elsewhere, He’s still God, and Christ’s work for us is still Christ’s work for us.
People have been staring at the stars and asking big questions for as long as we’ve had stars to stare at.
