A slight rewording of the definition of science.

Think about as science asking what can I understand about the {life, the universe and everything} that doesn’t require a supernatural explanation? Think about {religion\philosophy} as asking what can I understand about the {life, the universe and everything} that requires a supernatural explanation? With this viewpoint you can see that they are not necessarily in conflict but can actually be complementary.

How about:

Think about science as asking:
"What can I understand and the universe that I can attempt to avoid human mistakes and biases from coloring?

This requires ('cause I can't think of another way) that I have something that independent observers can check, test etc. separately from me and my biases. That leaves out a lot of thing including the supernatural.

Uncertaintly principle

I can accept that the universe has a net energy of zero, but that doesn't quite address my concern: IF gravity cancels out mass, souldn't we be seeing massive objects appearing all the time (today)because of the Uncertainty Principle?

Don't quote me but (well, someone will when they correct what I'm saying) I think there is a decreasing probability of the object appearing based on the mass of it.

Or I'm not sure that the gravitation "cancelation" can apply to a local single object (I am way over my head here) and we'd have to gather up a lot of energy in one place to allow a really massive object to appear.

Re: A slight rewording of the definition of science.

Yes it leaves out a lot of things!

Then perhaps you would like to go to this thread:
What is Science?

and explain what is left out.

You might start to understand that throw away one liners will not make you look very clever. You have to support what you say. Have a go at it in that thread why don't you?

Re: up in the attic and WAY off topic ...

Do we know exactly what gravity is, and what causes it?

Could you:
1) Explain why you ask this and how the answer will help the discussion progress?
2) Clarify what you mean by "exactly"?

We do have a very good (but probably incomplete) theory of gravity. However, I'm not sure if it answers your question or not.
