Your view of God is very limited, extemely limited my friend. Everything that you just posted is according to your knowledge, understanding, and wisdom. Your thoughts are not even in the same world as Gods thought, and neither are mine for that matter. But to sit here and say that God "cannot just be" is completely ludicrous. Yes, God can just be because He has always been. Again, just because we can't comprehened the infinite, doesn't negate the fact that the infinite is ETERNAL. He is the source of EVERYTHING. He has no need for a beginning because He never had one. God is not a man, that He should lie my friend. God has revealed to us that He has always existed. Now you either take it or leave it. The last day will declare His eternal nature to the rebellious. God bless.
