Why hands have holes between them?

Have we ever thought why our hands have space/holes between them? For me i think it's simply for another hand to fill em up. We need hands to hold, to comfort us, to guide us, to make us stronger and to keep us safe. How much we ponder the truth of security in our hearts. How we circulate our love and life between each other just like giving a wedding ring where it's a circle where there's not a beginning and there's no end. How life would be much better if all of us had that but it doesn't stop us from praying to have that... "Come in alive and go out the same way"
