You are still waffling, still evading, and making excuses, and you still cannot support your belief/claim.
What
@Subduction Zone said is true, you are using circular reasoning, and that’s logical fallacy, not logic.
You have claimed to have proof, but not once have you ever presented any equation to prove that the universe is eternal.
Sciences require evidence or experiments and certainly require data, to verify whatever model to be scientifically valid, as evidence or experiments are the only way to test a theory or a hypothesis. But the facts are, there are no evidence and no data, YET, to justify your claims regarding to the universe.
Lastly, I have never claimed that the Universe to be not eternal, I simply don’t know, because as I said above, there are not enough evidence & data to say it is eternal.
What we do know at present, judging by JWST’s discoveries, the oldest galaxies is about 290 million years after the Big Bang, so that would mean JADES-GS-z14-0 is at least 13.508 billion years old. JWST may in the future may discover more older galaxies, but not at present, and if they don’t, then logically, galaxies are themselves, “not eternal”.
Do you see there, Ben?
I am basing my logic about galaxies not being eternal, on the data from James Webb Space Telescope, hence not using circular reasoning, like the way you have been doing.
