You forgot that eight year olds don't stay eight year old forever.

1. No, they usually live longer, die, and face God's assessment of them.
2. The difference between the the sophistication of an adult and an eight year old is immeasurably less than that between an adult and the Creator/Savior/Judge God.
But then again, God cannot be measured, so... let's... just... not consider Him?
