It is more likely than not that God exists

I'll combine my arguments and my opponent's since they overlap quite a bit.1) Anything that begins to exist must have a causeMy opponent says that anything that begins to exist must have a cause. However, she doesn't specify why this is the case. She also claims that this cause is what we know to be god. This is a tautology as she is attempting to define god into existence. No proof was given as to why anything that exists must have a cause or why that cause is defined as god. God was defined as an "omnipresent and omnipotent creator." There is no link between "god" and the "cause" which my opponent hasn't proven exists at all.2) 2nd Law of ThermodynamicsMy opponent refers to "the law of thermodynamics." There are however four laws of thermodynamics: the zeroth law, the first law, the second law, and the third law [2]. I assume that my opponent is referring to the second law as she states that the Universe would be in a state of dissolution if it were truly infinite. However, that is a misrepresentation of the second law which I copied below:"The entropy of any closed system not in thermal equilibrium almost always increases. Closed systems spontaneously evolve towards thermal equilibrium - the state of maximum entropy of the system - in a process known as thermalization." [1]S = k ln WThis is commonly known as Boltzmann's Entropy equation. It talks about a specific type of system: a closed system with total energy E and tells us how to calculate the Entropy S of that closed system in terms of microscopic particles. Suppose we take a container of gas and consider all the gas in that container, each molecule in that container will have a specific position and a specific velocity collectively known as its "state" and the collection of the states of all molecules at any moment is called the miscrostate of the system. The microstate is constrained by two things: first, the positions of the molecules are constrained to lie within the container (which has volume V); and second, each molecule's velocity determines its energy, and the sum of the energies of all the molecules must equal E, the total energy of the gas. [4]The number of different microstates that can fulfill the Energy and Volume requirements is given by W in the equation above which is the measure of disorder. The only conclusion we can deduce from the 2nd Law of thermodynamics is that the larger the W is, greater is the uncertainty in what specific microstate will be observed when we (conceptually) measure at a predetermined moment. [4]3) Fine Tuning fallcyThere are many physical parameters in the Universe such as the Speed of Light, Planck's constant, and Newton's constant. These are arbitrary constants which establish systems of units. The only meaningful parameters are dimensionless ratios [5]. A common mistake made in assuming that the Universe is fine-tuned is to vary just one variable and keep the others constant. However, a change in one parameter may be compensated by a change in another. For instance, my opponent says that if the number of stars were reduced by a massive amount, the cycle of expansion and contraction would only last a year. However, if the mass in each of those stars were increased, it would compensate for the reduced number. My opponent kept all variables constant and only varied individual variables where as in reality, they are all interdependent on each other.4) Laws of the Universe My opponent claims that the laws of the Universe are "true, predictable, and constant." However, we constantly learn new things about these laws so they may not necessarily be constant. For instance, Newton's laws long considered to be true are now know to only be applicable in limited ranges and can't be used at very high speeds or very small scales [7].Furthermore, my opponent claims that morality cannot exist without god. She however provides no reasoning why god is a prerequisite for having objective laws.
