God is not real

Thank you for your arguements and respecting my request. As this is my first debate, forgive me for not knowing the formalities to be given during a debate.Rebuttal for the Kalam Cosmological Argument."1) Everything that begins to exist has a cause"Yes, I agree, but you do not specify that a cause HAS to be immaterialistic, I could just as easily say that everything physical that exists must have a physical cause and that the universe is physical, therefore it must have a physical cause (i.e. not God). Also the idea that you can have God create a universe thing ex-nihilo by pure thought when there is no time to think and that particular being is "timeless" is an excuse to evade scientific reasoning. "2) The universe began to exist."When and how did universe begin to exist? We still do not know that the universe had a beginning as the big bang theory describes it for fact. My opponent uses the big bang theory as gospel that the universe had a beginning at some point (called the singularity), but it is not so simple as it seems. We know from General Relativity and experimental findings that the universe did for certain expand from the plank second since the beginning of time. What happened before that is pure mathematical speculation based on the assumption that General Relativity holds before the plank time. I shall further discuss this in my arguement as to why a God is not needed for the universe to exist. Also the defense of this arguement bothers me, you say infinites cannot exist because it brings contradictions, like infinity-infinity=infinity, andinfinity-3=infinity.I do not see any contradiction at all, the reason why you see that there is a contradicition is because, you are assuming that infinity is a finite number. Sure, if I replaced the infinities in that "equation" with a finite number and got the results mentioned above, I would say that it is contradictory.But with infinity, it is not at all contradictory. Also, you claim that a "being" with infinite knowledge and infinite power somehow "created" the universe, aren't you contradicting your own assertion that infinites do not exist?My arguement as to why a God is not needed for the universe to exist.My arguement is based on mordern findings in theoritical physics and mathematics.If one assumes that General Relativity holds before the plank time of the expansion of space-time,we can ask the following question: What happened before the Big Bang?The answer is simple and it is general relativity that gives the answer. There was nothing, before the big bang, and it does not in any way give room for a God to have used a spell to create the universe. That is just forced conclusions drawn to fit one's wishful thinking. It does however say that space and time might have expanded from a singularity. Then quantum mechanics takes over to answer the question as to how matter came into play. There are however somethings that one must understand first:1) Empty space-time (or vacuum) has energy.2) According to Heisenberg's uncertainty principle, out of fluctuations in that energy, matter and its counter part anti-matter can be created spontaneously for small periods of time.If, however those particles are given a plank time together then they will collide and eliminate each other. But, if there was less time than that (such as the time before the plank second of the universe where only space and time were expanding) and that one of one of those particles of escaped the collision with its counter part (such as what happens in the event horizons of black holes) then you could have the creation of matter from "nothing". This of course has not been proven like God, but at least it has a sound mathematical basis. If one were to assume that general relativity does not hold before the plank time, then that would mean that a singularity might not have existed, and there would be no "point" of creation, eliminating the need for a god, the energy of space and time would have given rise .There are of course other theories like the multiverse theory that says that our universe is one of many universes in a vast multiverse that collide occasionaly with each other giving rise to the apparent "illusion" of a creation or big bang.Thus to win this debate my opponent must disprove all these theories (which have a strong basis mathematically) and either accept that the universe could have had a natural beginning or replace them with his own theory given the current data that we have from years of experiments and somehow incorporate God into that theory and make sense of the origins of the universe.Sources:Debunking the Kalam: Quantum Fluctuations:http://en.wikipedia.org...Plank scales:http://en.wikipedia.org...General Relativity notes: http://arxiv.org...Multiverse Theory: http://en.wikipedia.org...Quantum mechanics(preliminary course): Thanks!
