The absolute absurdity of God

[pocaracas]

That is all a nice theory (even though not the current preferred theory).

Could you point me towards the current preferred one, then?

What is the explanation of 'spacetime'? A brute fact?

Much like the explanation of 'god'. The basic necessary framework upon which everything else exists.

What metaphysics are you using to justify dismissing all causal principles for something that does not exist necessarily?

What do you mean?... spacetime necessarily exists.

Besides, I think metaphysics fails upon introspection. What came first, metaphysics or human reasoning? (I lean towards the latter)

Why does the universe seem to have a beginning and is heading toward heat death?

Conservation of Energy, I suppose... before the Universe, there was zero energy; after the Universe there must be zero energy, too.
Tell me, how does a Universe designed and created by a reasoning god also head towards heat death?

 An past infinite series of events is logically impossible. My 'God conclusion' looks conservative compared to all the metaphysical extravagance your theory has. 

Did you fail to read what I wrote?
For our Universe, what you say seems evident enough...however, our Universe is just a blip in the infinite vastness of the infinite spacetime. Sure, this Universe occupies some part of spacetime, but not all... the temporal part can extend to infinity past, even if no event happens within that part.
It may seem counter-intuitive, but it is a distinct possibility, if you think about spacetime as a single thing, a single framework upon which things exist and happen.
When you have a circle drawn on a 2D axis, that axis is infinite, but you only have things in it contained on the location where the circle is. And time in spacetime is equivalent to one of the dimensions on that axis.

The point is that I have reasons to believe in God that are rational and can be defended and are a better explanation that what you can come up with. I am not saying you are wrong, just that my version is superior because it does not require leaps in logic and a whole bunch of "it could that...and for all we know". Any charge that my beliefs are irrational (notice I did not say wrong), is simply not the case.

I don't remember saying that your beliefs are irrational.
I think they're wrong, as they imply the existence of a thing so far removed from reality that they may seem irrational to someone who simple extrapolates from the reality presented - Like I said before, more organized things arising from less organized ones.
