What is Man compared to a God?

Throughout the narrative of "At the Mountains of Madness" the biological specimens and artifacts found by the scientists are constantly referred to descriptions found in a book called Necronomicon.  The narrator claims that this text explains the aliens as Elder Ones and made man with self-awareness and free will as a cosmic joke.  Mankind is a plaything of greater and more terrifying forces found throughout the universe.  The main theme I believe the author is trying to portray is that no matter how advanced mankind becomes there are things about our world that are more ancient and powerful then anything we have perceived before.  Humanity is literally a child walking among giants.
