Hey there! You know how we can't see the wind, but we can feel it when it blows? Some people think of God in a similar way. They believe that God is not something we can see like our friends or toys, but instead, God is like a spirit. A spirit is something that is not made of bones and skin, but is still real and can feel and be loving.
So, when you ask if God is a spirit, many people say yes! They think that God is everywhere, kind of like how we can feel the love from family and friends around us. It's a way of explaining that God is special and helps us to be good and kind, even if we can't see Him. Isn't that nice?
