But I don't believe and I don't know. No one knows. That's why I'm an agnostic atheist. The only way you could KNOW is either you met god or you are a god yourself.
I know, and I am not God.
Let's take a different approach from the ones you offer, that of faith. Do you know the story of Moses whose eyes had to be shielded when God passed directly in front of him? Some read this story as a revelation about God--that God is seen best in hindsight; His presence, when directly in front of us, "blinds" us, as God is too bright to be seen. Sometimes we see in hindsight; perhaps because He is the expert in, "Don't let your left hand know what your right hand is doing," sometimes it seems all He leaves behind are His fingerprints.
What we know is that it is extremely difficult to prove God's existence in the physical dimension--the dimension that science can help explain. But is the physical dimension the only dimension? Some think there are indications that their are more dimensions than the one in which we exist.
It is also my understanding that the physical never ceases to exist--it may change form and substance, but it does not blink out of existence. If this is so, than all the matter we see now may have always been in existence. Let's switch from physical objects to the spiritual. Note, that we can classify the physical as 'matter'. Is it possible we can do the same for the spiritual? If we can, I would say for the physical, we have matter. For the spiritual, we have life, but perhaps more precisely, love. Is matter and love such an unbelievable/unknowable combination?
Just some more or less random thoughts...not provable in the physical world, of course, but perhaps knowable all the same?
