[Stephen King's It] How long has IT existed?
gpt
It arrived on earth in pre-history, crashing into the site that would become Derry, Maine in an event that looked a lot like a meteor impact.

The creature is, however, likely much older than that, and may have existed before the creation of our universe. It was born in the Todash Space, the darkness between worlds, and It is mortal enemies with Maturin the Turtle, who accidentally created our universe after a severe case of indigestion.
