You know, I was going to ask about that. Is gaia like a real god or is that just a name for the earth?

Gaia is not the common conception of her, as a goddess who watches over the earth. The Gaia that Caroline speaks to is the sentience of the earth itself which took on the name Gaia. It's a fine line, but a line nonetheless.
