Nobody is a creature millions of years old, before the earth was formed. It can be seen as white weak light his eyes see. You won't be hurt, he'll just watch you. She can talk, he learned it from observing people but he has not yet spoken to any person.
His eyes are just a slightly stronger white light. He doesn't look into your soul just at you. He doesn't talk much, he barely says anything. If you touch it, you will find that there is nothing material.
