<------------------beginningless and endless time---------------->
whatever..... no end, no beginning. Any moment in time is preceded by an infinite past....
<-------------------beginningless time, the time stops here.
An infinite amount of time passed before time stopped.
endless time starts here ------------------and goes on forever---->
A finite amount of time has passed at any point in time, because time has a beginning (starting point). This possibility is eliminated because something exists, and nothing cannot precede something that exists, because nothing cannot change into something or it is not nothing.
Yet, I will disagree with your claim that the last option is not possible because you say, "nothing cannot precede something that exists".
Ok, but you're being nonsensical. Nothing means the complete absence of everything. Nothing causes nothing (it has no properties that would allow it to cause something). Nothing does nothing (it does not act). Nothing doesn't change (it has no qualities to change).
If nothing exists at some future time
a, at any point past time
a, nothing will also exist, as there isn't anything, even a quantum mechanical physical framework, to cause something to pop into existence.
So, the earliest something that must have existed, assuming there was a beginning in time, wasn't preceded by anything at all, not even a moment in time where there would have been nothing.
No beginning to existence, so there isn't an earliest moment. There are plenty of beginnings within existence, from the perspective of conscious observers within existence, but they always emerge out of something existing.
It would be absurd to discuss how the first something to exist must have come about on the basis of the laws of nature since the laws of nature by hypothesis didn't exist before the first something, since there was nothing at all before the first something, not even a moment in time where laws of nature could have been in existence, and therefore no laws of nature either.
You're assuming a "before the first something, when nothing existed"... this is a nothing that somehow had the property of changing into something, so it wasn't nothing because it had the property of being able to change into something.
But it's interesting that so many posters should feel so aggrieved that UM can't seem to understand such basic ideas expressed so explicitly and clearly. It must say something about human nature but I know not what.
Maybe it says that feeling powerless in the face of sheer stupidity is really a bad feeling.
I'm just hoping someone writes UM an upgrade sometime soon. If they're just a neural net, you'd think they would improve (they're wrongness) over time, although maybe their is a maximum amount of wrongness one can achieve, even with the help of AI. Just joking!!! Don't upgrade UM, the world is fucked up enough as it is without having a super wrong AI loose on the intertubes.
Or is it just we want to affirm that our ideas can be expressed in a way that would be undeniably coherent?
We let preachers preach lies on street corners, so I suppose UM isn't exactly a threat to coherence.
I suppose arguing with UM is more for sport than anything. And really, I don't have time for it, but I have nothing lucrative, profitable, or enjoyable to do, so I do it instead of curling up in a ball on a couch.
