Self-evident truth is a thing

[Chas]

I see no reason not to think that the whole of existence is not an eternally-working process. If cause must precede effect, then there cannot logically be a single starting point of everything. To assert so is to force a logical argument to contradict its own logic.

That's the whole point, Ryan. There can't be a single starting point of everything unless who/whatever started it does not change and exists outside of time.
But it's impossible for anything that exists solely within this universe to go infinitely back in time, since everything in the universe is moving. Beginning is a necessary part of motion. Sorry to borrow from Thunderf00t, but saying motion has no beginning is like saying circles are not round.

Those are baseless assertions - they are not self-evident.


I don't know how, or even if, the universe began, and neither do you.

The Kalam argument doesn't prove anything, so there's that.
