An intelligent atheist might say God is unlikely, improbable and unproveable, but not impossible

Intelligent? That's barely literate. All the indicators are that God is impossible other than in terms of highly specialised fiction and absurdist make-believe. He he thus on the same level as the Starship Enterprise and Mr Bean - I derive great joy from both these latter, even the former, but never in the sense of literal truth or anything so conceited as sacred. Not only do we do such concepts a disservice by taking them literally, we do ourselves a disservice by allowing that our mythic dreamings can be in any way true.

If we allow for the God of Abraham being real, then we must allow for them all being real. That's quite a pantheon of possibility you have there, which must also include astrology, ETH-UFOs, the Loch Ness Monster, Ghosts, Trolls, Goblins, and a myriad of subjective supernatural bogeyman humanity has created by way of folklore down the ages. Far better we understand these things for what they are than what they, most evidently, are not .
