“I refuse to prove that I exist,” says God “for proof denies faith and without faith I am nothing”.
“But,” says Man, “the Babel Fish is a dead giveaway, isn’t it? It could not have evolved by chance. It proves you exist, and so therefore, by your own argument you don’t. QED.”
“Oh, dear”, says God, “I hadn’t thought of that”, and promptly vanishes in a puff of logic.
That was Adams' take on God. Dea's response is a hair different:
“It proves you exist, and so therefore, by your own argument you don’t. QED.”
“You cheeky little monkey,” says Dea, “Okay, have it your way,” and hits the "recall" button.
There's a million reasons why Dea might instigate these raptures. I'm personally a fan of the answer being "we asked for it!"
There is, however, some prior art, based on your description of Dea. It sounds very similar in nature to that of Hindu deity Brahma. Brahma is seen as a creator of sorts. Now I know the Hindu faith is a widely varied one, so I can't speak for all Hindu on their world myth, but I love Alan Watt's rendition of it because his is so incredibly literary, so it is the version I will channel here, as I remember it.
He describes Brahma as a god with many faces, one in front, one for each living creature in back. He describes Brahma as the dream and the dreamer, all in one. All of reality is him, and he's dreaming about all of reality. He dreams up a play so extraordinary that somewhere along the line he gets lost in the beauty of it all and forgets that he is dreaming. Thus we all forget that we are all Brahma, dreaming. We all forget that we have the face of Brahma on the backs of our heads, being dreampt wherever we go. We all become so invested in our characters that they become us and we become them.
In the Hindu faith, the world goes through four phases, each one less beautiful than the last, and the last is the Kali Yuga. In this phase, the demon Kali emerges and reigns. And from this, great chaos is sown, until Vishnu, incarnated as Kalki, his 10th and final avatar, comes forth to do great battle with Kali. And as Kali and Vishnu battles, Shiva dances. Shiva dances the Tandava, the dance of the cycle of life. This Tandava is the source of all creation, preservation, and dissolution that is life. It is the cycle of life itself, at some level. Now this dance comes in two forms. For most of the course of creation, Shiva dances the Anada Tandava, a joyful dance celebrating life itself. But in this dark hour, as Shiva watches his friends fall, he becomes more and more distraught. He dances the other part of the dance: The Rudra Tandava. The pounding drums of his dance would shake you to your very core as the reality of the dance comes forth. He dances this with such ferocity that the ground begins to crack under his feat. The world begins to break as the dance goes on. Fires erupt from below, consuming all those under him. It consumes Kali, Kalki, all of their combat, and the whole sum of everything. All consumed in the final dance that is the Rudra Tandava.
And thus, when he stops, he is alone, on the stage. No other gods survive. No mortal survives. Even the reality of the dream does not survive. This finds him center stage, peering out at the house of seats in the theater we've been performing in.
And to draw the scene closed, he takes a bow, turns, and moves to exit the stage. And as we see him turn away, there's the face of Brahma on the back of his head. Just as it had always been. Just as it has always been for all of us, our whole lives.
And thusly, the cycle begins again.
