A Problem with Cosmological Arguments like the KCA

They need careful and consistent use of the term ‘Universe’. If you define ‘Universe’ as our universe that started from the big bang, then tentative answers from the science of cosmology can be used to suggest possible explanations regarding how our universe began or arose.

But if you define ‘Universe’ in a philosophical way like ‘everything non-God that exists’ (it is up to the proposer of the argument to define terms, that is just my example) then you have the problem of demonstrating that it had/has the properties you need. Eg if you are using KCA that it had a beginning, or it requires an explanation, or has a Prime Mover, or whatever is your chosen approach.

Due to this problem (and others) I think Cosmological Arguments can’t demonstrate that God exists.

(Background – I have been invited by a Christian member here to present an argument as an atheist. I am aware that this is a Christian Apologetics site, so I want to be gentle and respectful in this. To be helpful I have chosen this issue because it is something that should help sharpen your apologetics tools, especially if I am wrong.)
