Ok, so this is what I said:
Here’s another word I made up “abb”. It means ‘that which is non-existent but exists’.
And this is why you replied with:
Of course “abb” is not meaningful, but just making up words does not tell us something profound about the universe.
This is an assumption. We don’t know this, but you are acting like we do. What evidence do you have that existence is infinite?
So you clearly understand that ‘that which is non-existent but exists’, cannot be true. You understand that abb is 100% false. abb cannot be a meaningful word, theory, belief or statement. So why then do you reject the following:
Existence has always existed and will always exist
If Existence has not always existed, then you are saying that abb is true. Because let’s say the universe had a beginning. Was this beginning in non-existence, or Existence? In other words, was this beginning in/via an existing thing, or a non-existent thing? If you say non-existence (non-existent thing), then you are saying that non-existence existed (meaning that you believe that abb is true). If you reject abb, then you are rationally obliged to commit to the following:
Something has always existed and will always exist.
If you then reject that we don’t know if it will always exist, then I put to you the following falsification of said potential rejection:
How can something go into or become non-existence? Do not confuse this with something becoming non-existent in relation to what it was before in your reality. For example, your dog dies. Your dog is no longer existing as your dog in your reality. This does not mean that your dog went into non-existence or that it became nothing/non-existent. It means that it changed into something else. When you burn something and it turns to ashes, those ashes don’t then turn to nothing/non-existence do they?
Do you see where I’m going with this? So again, you reject abb. If you reject abb then how can you reject the following:
Some existing thing (which I will call Existence) has always existed and will always exist. Some existing thing, is infinite.
