The idea of God always existing

[Mystic]

If we remove physics from the equation aka pre-universe who is to say that the uncaused cause in a sense is a fluctuation in matter or something else?

This is a good question. What we know of matter is that is time bound. There is movement and part of it's properties is time. Does it really make sense to say tiny particles all each caused time or that space caused time all of sudden to exist while there was no time?

I think that it's impossible, and anything physical doesn't seem to be able to cause time to begin.

So I conclude it must be an powerful magical type being, because it needs to bring into existence time which is not in existence.

Abstract metaphysical things can't bring time into existence or matter which has time as a property, so it must be a personal living being that has will.

How does one give personal characteristics or deity based characteristics to this cause?

From properly basic knowledge of him (spiritual instinct) or personally I think reflecting on the nature of morality and greatness will point to an Ultimate Moral Being.

But if we ignore that, and look at the fact it has personal will, we can see it has high intelligence, and we an associate moral thought with high consciousness and it seems we been given a lot of good, opportunity to be honorable, etc, which shows good will on part of the First Cause Being(s). We can also see it's immensly powerful and is a magical being.
