Your claim doesn’t have anything to do with my original point other than semantic sports over whether the sun is a head. Philosophy and theology also don’t determine reality. We can only discover it through these means, the same way we can discover reality through science. The simple fact is that some philosophical, theological, and scientific hypotheses are closer to reality than others. The only way to dispute that would be to argue there is no objective truth, which is a self-defeating claim.
Again, OP is making a meaningless argument.
Is the statement that there is no objective truth objectively true? If so, there is some objective truth, and the statement is false. Like I said, it’s a self-defeating claim.
