My view is: does it matter? Are you going to change the way you live life to satisfy yourself that what you're witnessing is purely nature? As an intelligent adult, you seek out interesting experiences. Your son does the same.

Don't worry about semantics. Just keep respectfully and sensitively following your son's lead. Children who are eager and enthusiastic learners will not allow otherwise, but you already know that first hand! smile

What is to give light must endure burning.
