I understand it might belong to the Abrahamic set. In the sense, if we assign properties to this God, I agree with you. The same the Michelson Morley experiment tested for the luminiferous ether. But in our collective understanding, there is no need to postulate a 'creator' or whatever.
The way I am reading this is: We can't rule out whatever we don't have a clue about. Now by definition, I am agnostic (or even atheistic) about Gods I have not dreamt up yet. But I don't see a need to go out and bat for what I haven't dreamt of yet.
If people were to argue they feel they have a purpose or even think there is a purpose then there is no argument there from me. Just an opinion? Trump was a good president is an opinion. Not all opinions are equal. Some opinions have foundations built on sand and some on rock.
What can you prove Paul? All we can do is provide corroborating evidence and go where the evidence takes us.
