who says time is linear either.
Of course we don't know that it is. Time is the biggest mystery of them all.
But since we know there's an irretrievable yesterday, and another yesterday before that, and before that, going back a week, a month, 10 years, 5,000 years, etc. It's really understandable that someone would feel that since this progression goes only one way, as we are in a constant, imperceptible state of "now"....that the days we can trace back, and the lives that could trace back, and the species and civilizations that could trace back, could lead back to a beginning moment.
No one knows about the origin of the universe. I've never professed to. I'm not being presumptuous, but only giving my opinions on it.
not only that but the act of creating suggests time existing already.
Wrong. that's because you are thinking of it in a limited, human way. What we think of as the time in which a linear succession of events (God decides he wants to create a universe, THEN, he creates it, etc.) is STILL THINKING INSIDE TIME.
The only time I'm proposing...it's like an object, in God's lap...the "left" extremity of which is the first moment of time, the "right" extremity of which is the last moment of the universe.
We can't conceive of consciousness unfettered to a perception of itself within the bounds of linear time, which is one thing that makes it sound all the more plausible to me...religious people always say, "We can't understand the awe-inspiring, complex nature of God."
But rarely do people get a real taste of what that means, "We. Can't. Understand. God."
Plus, there's absolutely no reason to assume that the act of creating time wouldn't be a self-referential creation as well, meaning that, yeah, God was pure, timeless being, and then created Time when he decided to act.
Then, yeah, he creates, for himself and for us, time.
Creation is a start of something.
I could easily imagine that the very act of Creation (which necessitates a 'beginning'...something wasn't there and THEN, it started to exist...) created time, as a medium for it's own expression.
