Where do people come from?

Our family home evening lesson last night was on Adam and Eve (and on our identity as children of God). We've been following the lessons out of the sunbeam/nursery manual for primary, so this lesson followed a series of lessons on the creation of plants, animals, etc. Andrew understood that Heavenly Father created the plants, the fish, the birds, and the animals, but he was having a harder time grasping the creation of people.

I asked him, "Did Heavenly Father create Adam and Eve?"

Andrew said, "No."

Curious, I pressed, "Where do people come from, then?"

To which my pragmatic little boy answered, "From their houses."
