There is no external cause of the universe

It is disappointing that despite my proving the implications of Pro’s argument he stresses and reiterates that he affirms the finite beginning of the universe. Yet he maintains that every state of universe was caused by a previous state of universe (for eternity), he again clarifies:“To clarify, my argument is that the universe had no beginning state (a state of the universe that was preceded by no other state), but it still had a beginning in the sense that every state existed at a time less than 13.9 billion years ago.” Anyone reading the above quote would understand that it is nothing but a meaningless and contradictory statement. And this is the only reason that I had to fill in the gaps and insert assumptions in order to make them meaningful. It is either a case that he is confused about his own argument, or that he is deliberately being irrational. You cannot claim that every state of universe was preceded by another state of universe, simultaneously claiming it had an absolute beginning. He asserts “the universe had no beginning state” which literally means he believes the universe is beginning-less (and apparently endless). Yet he claims that it had a beginning “in the sense” that every state is a finite period old. I had to assume that he means to refer the space time state of the universe after start of the expansion to be finite; and he considers the initial quantum vacuum prior to be eternal, or beginning-less. He repeats that I don’t respond to the FLRW metric that says every state of time is half-open. It was irrelevant because that had nothing to do with supporting his argument; since he acknowledges the finite beginning of time along with the birth of universe. It is clear he maintains and defends an argument which is either very confused or dishonest.Does the universe have no external cause? I don’t want to repeat my argument in conclusion; it has been proven continuously that the universe could only be without an external caused only if it was self-existent, eternally (without beginning) and out of the necessity of its own nature. We have seen ample evidences from philosophy and science, that the universe is not eternal, self-existent and necessary, but contingent and began a finite period of time ago. It follows logically that the universe had an external cause, since there was a moment when there was no universe at all.All Pro has done is to attack red herrings and ad hominem by accusing my arguments of plagiarism, which was desperate attempt of distraction from truth. I again ignore those red herring attempts. Let me again remind all to go study this article from which I largely quoted to have a thorough and detailed analysis of cosmology. http://www.reasonablefaith.org... Readers judge the evidences and reasoning, ask yourself “does the universe have no external cause but exists necessarily and eternally”, be open and honest to this question without letting your presuppositions come against your quest for the truth. Then you will definitely be intrigued to search deeper questions like why the universe exists at all! The universe has indeed an external cause of its existence and it points out to a profound objective meaning and purpose behind its existence. Don’t forget to vote for the reasonable side.
