The first argument I will be addressing is the cosmological argument. It basically goes as follows. Everything must have a cause. The universe must have a cause. That cause is god. The Kalam argument simply adds in an assumed finite limit to time.
1: Quantum fluctuations do not have causes. They are created from nothing and go in to nothing. The first statement is demonstrably wrong.
2: There's no reason why time can not be infinite. The argument by theologians and philosophers are simply making the same err as the Zeno paradoxes.
3: We have no example of nothing as would be the case before existence; nothing can be concluded about the properties of preexistence.
4: The big bang was a singularity. We do not know what happened before the big bang.
Assuming the universe was caused:
1: There's no reason to believe that cause still exists.
2: There's no reason to believe that cause was conscious.
3: There's no reason to believe that cause was a being.
4: There's no reason to believe any specific characteristic about that cause.
Finaly, there's absolutely no rational connection between "the universe had a cause" to "the god of my particular religion exists".
