If I'm not mistaken, he's not saying that it's impossible that you are right. He says it is merely possible, though not necessarily so. Proving that something is possible does not prove that it is actually so.
It is rational to choose it as an explanation, it is irrational to choose it as the explanation.
Well said.
I'm not trying to argue that gods cannot exist. I'm not trying to argue that we aren't in a simulation. I don't have access to these truths.
All I'm trying to argue is that we all have to make a personal choice, and we can rate the rationality of that choice.
We must choose from among the following options: (GalacticEmperorXenu) (Allah) (Brahman) (Shiva) (FlyingSpaghettiMonster) (Yaweh) (InASimulation) (It'sAllADream) (i'mABrainInAVat) (IAmGod), ad infinitum
I'm trying to show that the only rational choice to accept as one's belief is the simplest. The one that requires the fewest things to believe in.
The only extraordinary claim my belief system contains is the following: "Either the universe as we know it is eternal, or it spontaneously popped into existence from nothing."
I don't deny that that's extraordinary, and I don't claim to be able to prove it. It doesn't affect the strength of my argument, though, because no one can come up with an explanation that doesn't involve something being eternal or spontaneously popping into existence from nothing. All of the options I mentioned above do. The difference is that mine does not require me to believe in any OTHER extraordinary claims that have no evidence.
