Well Man is ape
like, whether one considers him an ape or not.
But OK. First of all, I presume you
don't think God is an old man with a white beard. After all, Christ was God incarnate in the form of a man, while God is otherwise a spiritual entity, right? So what does "in the image of God" mean, then, since it obviously can't mean God looks physically the same as a man. What it means, surely, is that Man, like God, has rationality and an eternal spiritual component, a soul, that does not have to die with the body. So it's not a statement about the shape of Man's body, but about his inner essence. (Medieval philosophers even speculated about the soul being "infused" at some stage into the growing embryo.)
There's a longer discussion of what the phrase may mean here:
Image of God - Wikipedia. It has preoccupied people ever since the dawn of Judaism (and later, Christianity). But note that nowhere does it say people thought it meant God has the same physical shape as a man.
