Only if beings on other planets exist, which we can't prove. All we can prove is that the universe is vast in size and contains an extreme number of planets, stars, etc. To make the jump to assuming they must contain life assumes a knowledge of God outside his word that we just don't have, unless, of course, I'm missing something.

Is the Mona Lisa the background to the mountain behind her? Or does the mountain exist to add to the focus (i.e. the woman in the painting)?

If the background appeared naturally through evolution along with the woman then you could claim they're equal and that there's no reason to think the woman is special. But when God is involved that all goes out the window and it becomes about understanding what he actually did, not what he maybe would have done when looked at through the human lens of what's "likely" or "feasible". It becomes about finding out his goal with the painting and there's no reason to assume the mountains behind us are anything more than empty rocks that exist solely as a background to us and for us.
