I don't know if this series has been posted before, but if I've forgotten, then maybe it's time to bump it, not least for those who don't want to trawl through all the past history of this thread (That's my excuse anyway.)
The motion is "We'd be better off without God"
And the speakers, on both sides, are a cut above the average.
My reaction , though somewhat predictable, is this:
Even if (belief in) God makes us "better off", it doesn't make God true.
If we devoted as much time and effort into philosophising about what would make the world "a better place", in whatever field you care to name, whether it's human rights, art, music, comfort for the bereaved, law and order or whatever) as we (as a species) do about promoting religious falsehood, (official sanction and daily exhortation) we'd obtain some pretty spectacular results, maybe better than those obtained by belief in God.
