So, you admit you have nothing. These are religious debates, so I've been trying to use logic and cosmological arguments. Also, scientific cosmology is still philosophy. There is the philosophy of science tho.
All you are doing is making assertions KCA is invalid.
Then, show us how the big bang had a beginning. The ToE already had a beginning as a cell was given to Darwin. Darwin didn't create the ToE. What he did was explain how it worked.
The big bang cosmology already had a beginning as it sounds like big bang ex nihilo or big bang from nothing. IOW, one can't state there were something like quantum particles as nothing. Thus, Stephen Hawking died trying to find evidence for his beginning. Nothing should mean nothing or what the Bible describes as the void.
