Heaven

This morning when I was getting the kids and I ready for the day, Cayden was singing I am a Child of God to Ellie. I asked Cayden if he thought she knew that song and maybe sang it in Heaven. He said yea and then I asked him if he remembers being in Heaven and he said, yea with Ellie. I then asked him if he knew where Heaven was and he said, yea it's in Heaven. I then asked if he knew who was in Heaven which he responded, George Washington. Where in the world do they come up with this stuff?
