Uhm, how do I respond with this? Or should I not respond at all? In hindsight, I've already responded to it, as such, the latter question is well, out of the question.
In any case, could you enlighten me to what you meant in this statement so I may not misinterpret it? Thanks!
To OP: Hmmm... So the main point of the debate is that if believing in the inexistence of God is folly.
Here's my opinion: God must exist. A creator, a bringer of life, a prime mover, whatever you want to call it, a "God" must exist. Why? Because it would be irrational if there shall be no beginning. Everything has a beginning, and the source of that beginning, that prime mover, is the essence of God.
Now, whether or not a personal relationship with this God, or a submission to this God must be established is irrelevant. Indeed, to argue about religion with this question is irrelevant, for religion accounts for a relationship with this God. However, we are not to dispute this relationship, whether or not it should be established, but rather we are to dispute the existence of God. Simply put: the existence of God is unequivocal. There must be a beginning, a sole one, to make it rational, to make it logically sound. Now to ask, "How did the beginning begin?" or effectively, "Who created the creator?" is irrational, as this will go into infinity, and that wouldn't make any sense, would it?
In perspective, what defines rationality, anyway? What defines logical thinking? Is it not true that we ourselves have defined what is logical or not? If so, could it be possible, that with our feeble minds, we may think something as rational when it is not? That there may be reasons to things that reason itself could not understand? As such, then how can we be sure that the existence of God is unequivocal, despite its logically sound reason?
But, the rationality remains, for it is this rationality that makes sense to us, and therefore, bound by this absolute logic, we can infer safely and soundly, that God must exist, and to think that God does not exist, is nothing more than, as what the OP have said, folly.
