@joefromchicago,
Quote:Why couldn't a hypothetical wall exist without an observer?
It requires the mind's eye to observe it.
Quote:I don't know how theists "know" that god exists.
That is a tricky question to an atheist or an agnostic but someone who believes in God should know what criteria they use "to know God exist. People like you and I can only assume that a God does not exist because a God has never taken the time out to show itself to us.
Quote:I'm pretty confident, however, that things exist without an observer, even though I can't "prove" their existence without observing them.
That is the approach I use as well in my everyday life. It seems to be the only sane approach that is required to navigate through what we call reality.
Quote:You're mixing terms. The "reality" that I'm talking about is the tangible or perceivable reality of an object, not the reality of a belief, which doesn't make a whole lot of sense.
Are you suggesting that God is not real to a theist but only a figment of their imagination, or just something they make up "like a belief that is not real?
Quote: Do you think that if you were born in Afghanistan, your reality about religion would be a Christian reality?
I have no idea what you mean.
What is the likelihood of someone born in Afghanistan having a christian belief system. A Christian's belief "Christ" is part of some peoples reality just as a wall is to me and you.
It seems that your environment or "what you are exposed to, shapes how you believe and what you call real.
