That's the point, someone may say that is a foolish and silly question,
not really. Someone is brought into this world at age 20 and his mate
show up. Can you imagine waking up one day as a grown man with no
memories of the past, do you no how to walk or speak. Not only did this man
speak he named the animals. Procreation was easy he just observe the
animals but the rest of his knowledge, hummm.
