I know this will be hard for all of you to believe, after all, many of you have wasted years thinking otherwise, but try to overlook your emotional attachments and consider this rationally.
I think we can all agree that if
an existing god exists, then a god exists. (And by "an existing god", I mean, "a god that exists"). So, to prove that a god exists, I merely need to prove that an existing god exists, which is simple enough.
I think we can also all agree that for any proposition P, either P or not P must be true (this is a basic logical tenet called the law of excluded middle. en.wikipedia.org/wiki/Law_of_excluded_middle
). For example, given the proposition, "John owns four cats", we can conclude that John either has four cats, or does not have four cats. Simple enough.
Anyway, back to existence of a god. The proposition I am trying to prove is "an existing god exists". Given this proposition, from the law of excluded middle we can conclude that exactly one of these two possibilities has to be true.
- An existing god exists.
- An existing god does not exist.
Look carefully at the second possibility: it's a contradiction in terms! Clearly, it is not logically possible for something to be existing and to not exist at the same time. Hence, we can clearly eliminate this possibility. Since we established that exactly one
of these possibilities is true, and that that second cannot be true, we must conclude, however improbable it may seem, that the first is true.
So, we've established that "an existing god exists", and we've already established that that implies "a god exists." So there you have it, a logically irrefutable proof that a god exists!
