Who's to say for instance that we aren't all God, simply enacting the collective will of one all-powerful force like the Brahma?
Possiibility doesn't mean you know it for a fact that you're an all-powerful God.
The answer is no.
Perhaps my instincts know, but my consciousness is blocking out what it all means?
Then you clearly don't know it for a fact.
So the answer is no.
Haven't you ever just had a feeling that something was the case, even though you couldn't prove it?
If you can't prove it and it's a feeling, you don't know it for a fact.
The answer is still no.
Have you ever seen any of those times come to fruition, not fully understanding how you could have known or done the things you found yourself doing?
If you don't fully understand it, you don't know it for a fact.
The answer is no.
Perhaps in that, it is known as fact in spite of the environment, in spite of one's own conscious knowledge of their retention of this fact.
If it's only a possibility, you do not know it for a fact.
So the answer is no.
You could have answered all of this with a "no."
Or that the question is ill-defined.
