Yeah we do see through a glass darkly but God continues to give us clues and bits of truth all through our life. You do open a can of worms with this, but that is ok because we prolly should discuss it some.
First, Our scientists do know now that our heart has a much greater thinking capability than our brain (HeartMath.org) and I personally think that our heart is somewhat physical somewhat spiritual. Or at least there is some sort of nexus between them. So It is entirely possible that it is on a spiritual level. The stars do not have a physical heart, but are they without a spiritual one?
And what about that scripture that says something about, the very stones would cry out to God? I heard a testimony from a gal (online) where she was having a visitation and Her and Jesus was talking and Jesus made the statement to her that, her cat contemplates God better than she does. I got no indication that this lady was speaking an untruth.
In another testimony (different lady) was taken in spirit to Heaven and was giving testimony about it, and she said she saw children playing around a tree there and one little girl was reaching up to pick a piece of fruit from the tree. When she would reach up for the fruit, the tree lifted it's branch higher out of the reach of the little girl Then it would lower it's branch so the child would try again, and do it again. Almost like teasing and playing with the child. Do trees have a sense of humor?!
I know that may sound insane, but...in this natural realm where deception is rampant and all truths denied us, how can we be sure that this is not true? Is anything too hard for God? And if all of creation is groaning for the Lord's return, then how is that possible unless there is more truth to it than we are being shown by the world? Our understanding tells us, that is ridiculous and yet, we are told not to lean upon our understanding.
I am inclined to believe that all of these things are possible with God. Can an animal contemplate God without thinking? I think not. Scripture tells us that it is beyond the comprehension of man all the truths and goodness of heaven. So perhaps you should not be so quick to not believe that these things are possible.
Are these things metaphors? Maybe maybe not. I know that scripture uses metaphors, I will not argue that. But is, it's a metaphor, overused by us to justify rejecting things that we do not understand? Perhaps! Lord help my unbelief!
