But the problem with logic, as useful as it is, is that you can use reason to argue ANYTHING to be true. That's why we use empiricism to gain our knowledge.It's just a matter of words
some call it Universe
some call it Energy
some call it whatever
I call It OUR FATHER
GOD.
It's one thing to call on a "First Cause" to explain how the Universe was created. It is something else entirely to prove it was your version of this "First Cause" that was responsible.
Yes, it is a matter of definition of terms, which makes it just as logical to believe as it is to disbelieve from a formal logic premise if one defines 'God' correctly.
Yes, I made that point earlier, and as for empiricism, it's circular reasoning, since repeatability by others is the goal. It can't recreate such events as 'big bangs' or 'evolution' hypotheses.
