Common mistakes
Don't say
"Everything needs a cause, so God."

Don't say
Stopping at 'a necessary being'.
Instead
State explicitly the further steps to a personal, non-physical, agent cause.
What would change my mind? — Christian position
A defensible account of the physical world as metaphysically necessary would neutralize it.
What would change my mind? — Skeptical position
Strong independent support for the PSR plus the arbitrariness objection to necessary physics.
Why does this matter?
It targets the deepest possible question and does not depend on any scientific result, which makes it unusually durable.
