Kalam Cosmological Nonsense

[median]

Premise 1 is flawed: A carpenter can build a house where none previously existed. Prior to Newton and Leibniz calculus did not exist, now it does.

No, it's not flawed. A carpenter doesn't create anything ex nihilo. He merely reassembles material that was already in existence (1st law of thermodynamics). Regarding Calculus etc, those are not 'things'. They are abstracts. A mere discovery is not a creation ex nihilo. If you want to defend that claim, please do.

Just for Fun:
Define 'global universe'. What does it include and more specifically what, besides God and silly examples like pink unicorns, does it exclude?
Define the essential properties a real thing must have in order to exist.

For short, the global universe includes the totality of all physical/energetic existence (i.e. - the totality of all things that exist). We do not know that our local universe is the totality of all that exists and there certainly has been no demonstration of any "creation ex nihilo". There are a vast number of possibilities that have been postulated by science (multi verses, etc). This is why I said the correct response is to admit ignorance and withhold judgment, instead of leaping to "Yahweh did it." Attempting to solve a mystery by another mystery doesn't solve anything.
