Where in the Bible does it say that God has always been? I don't know the Bible very well.
And why is that any better a starting point than the p-brane theories which suggest a multiverse which as always been? It does come down to we both 'don't know'.
Sorry but the Bible isn't my subject of interest. That is something I don't claim expertise in.
Your evidence is the Bible. I'm just asking for where it is explicit about the eternal existance of God. It is yours not mine. Where is the chapter and verse is all I'm asking.
