I personally think that one of the most important phrases I have ever uttered is:
"I don't know."
We
all want to know the answers to what I call,
"The Big Kahuna Questions." So, we begin with observations (such as, "the universe seems to be expanding"), and inevitably wind up with Big Kahuna. Other people vehemently disagree, and guess what: they
also wind up with their version of Big Kahuna. I guess it's just human nature. When we observe something, we are driven to explain it.
In every "scientific" statement, there are two distinct parts:
observation, and
interpretation. "Aye, there's the rub." 
Interpretation is where we begin to get into trouble.
Some people "observe" things and see "science," while others observe the same things and see "God" or "gods." But, I think that we lack any
objective basis from which to "conclude" which one of these viewpoints is actually correct. Some people look at a pin and wonder how many angels can dance on its head. Others do not. So, maybe we all should agree to disagree. We will never actually know what "the elephant" looks like. An observation can be
useful to us, even if we have no way to know – and we very often don't – if it is
correct.
I have seen science,
and I have had unexplainable, "mystical" experiences. I was once startled-awake by a voice. I
listened to what that voice was saying and it led me out of a difficult situation. My grandfather once gave a warm coat to a man at his front door who suddenly wasn't there. I don't
try to "explain" these things. I don't think anyone can. But you can never tell me that these things didn't or couldn't happen, because they
did. As the Good Book said of Mary,
"I treasure them in my heart." I embrace
every mechanism that we have to understand our world and our very-brief place within it. I don't need to "know it all."
