A god like Jehovah certainly doesn't exist.
Maybe this universe was caused intentionally. Nothing prevents that. But is hard to accept a god who intervenes directly in the universe.
I understand the need of the concept of God. But the only healthy concepts are the traditional mainstream Christianity. A god who acts directly only after people die.
Many X-JW's turn to atheism because the Solar Scriptura adopted by WT. I think atheism is pointless. Agnosticism seems to be more practical.
