In the sense that God has control over people, he's real, whether you believe in him, or think He's a construct.
I suppose if God is real then he's the gardener of the earth. All the plants and animals evolved and grew from the seeds He planted. He grew us out of tadpoles. But we, his most beloved and closest to him in our realization of him, and desperation to please him, have only been able to drop dead animals at his feet, wagging our tails, and trying to be good
, while the whole garden has been destroyed by our dog gangs. God has no control over us. Hell is an empty threat, and heaven is just God's putting our pictures up in his house. It's just a shrine to his dead pets...
There's only one garden and one house, and we're just here to pee on the carpet.
