I thought about sending you a PM but it might make an interesting open discussion.
I've seen you express the lack of good pro-God ex-Witnesses to engage with. I don't know about ex-Witnesses, but there are a few Witnesses who've written on these issues. I wonder if you've come across them and if you could comment on how you find the quality of their arguments.
At the moment we've got Gerard Gertoux for example defending the biblical flood (I hope the link works without having to join the site):
James Steward has long written and continues to write on similar themes on his website:
Hal Flemings wrote a more general defence of theism published by University Press of America:
And various Witnesses contributed appendices to his book on the Bible defending science in the Bible.
Have you come across these? What do you think?
