Suppose God (christian) was proved to exist (imperically)?

You really have no idea what goes on here. Are you asserting that ideas should never be challenged and that discussion of anything is useless unless it produces an immediate and material result?
Because if that's how you feel, you really should just stick to those watch forums so you can find a good scrambled egg recipe or torrent for your TV shows.

You're challenging what ideas? And for what reason? I don't get what you're talking about.

Anything that I care about. Your most fundamental ideas are the ones that should be challenged the most.

What do you know for sure?

Just about nothing. Certainty is a red herring and a useless concept, which is precisely why continually re-evaluating and discussing your ideas gives you the best chance of maintaining a truthful position.
