scotchfaster. I had all the same questions. In science and religion. Mal. 3: 10 Prove me. Test me in this. God is asking you to prove him. Look it up.
If I pray to Jesus Christ for a healing (according to his will) and the person is healed of cancer, a heredity blood problem, don't need glasses any more, I'd say the name of Jesus means something. Doctor's gave up on her.
If Mohammad healed I'd pray to him. But as I said once the Holy Spirit enters your life he will modify your life, character, and personality. Teaching of any kind alone will not do that.
For a change look at all the christians who are not hyprocrites. They are a majority but quiet and peaceful.
Then there are the prophecies. No book anywhere can claim what the Bible can. Every prophecy came true 100%. I can not predict what will happen five minutes from now. Some prophecies have hundreds of facets all are accurate.
Just read up on these things. Go to a Bible book store.
"Too often people will jump into a multiverse or circular universe theory to explain what happened before the big bang when in reality we don't know and currently (and perhaps will always) have no way of knowing.
Well, the multiverse explanation is the only one we have (I believe) for why single electrons, fired one at a time, show interference patterns. Maybe we'll find another explanation, but the multiverse interpretation of quantum mechanics is currently the best one we have.
You're right that we don't have any way of testing many of these theories, so they're little more than guesses. There's another theory as to the origin of our Universe that hasn't been brought up yet, which is that our "Big Bang" resulted from universe sheets (or "branes") colliding, which is discussed here in String Theory for Dummies. Or our entire Universe could be a quantum fluctuation...
Anyway I tend to think that we'll never know what's outside our Universe, simply because we are bound by its laws and cannot see out.
