Chasing Our Own Tails
It is said everything that exist lay within all things that don't. The latter being far greater. Some lean on faith for what they cannot understand. Some simply block out anything they don't understand or care to think about. Still others make up things and declare them truths for what they can't comprehend. Each are much like the unconscious person I mentioned above.
There is yet another way to approach this (since no one can understand through one's human faculties). For the sake of definition I will call it 'taking a stance'. If one simply takes a stance (position) that the universe (and all the people in it both good and evil) is what it is and accepts that, one becomes more attune (one with it). Some religious philosophers called it surrendering to 'God's Will'. I'd rather think of it as leaving one's ego behind. Another way of saying it is 'going with the flow'.
You Can't Beat The System
The short and long of it is, enjoy the ride while it last. Whoever or whatever the creator is/was or what ever evolves is larger then we who are only temporary reflections of that. To do otherwise would be like a shadow (reflection in a mirror) trying to outwit that which is standing before it.
Did anyone them self personally hear from so-called God?
Of course not and no one ever will because (if you read what I said above) God is "selfless". He/she/it is above all this. Genesis in the bible gives us a hint when all our troubles begin. It spoke of a war in heaven. In essence a battle between self and selflessness. If we wish to be more like he/she/it the best advice is to become less attached to our self reasoning's which sets us farther apart in a judgmental way towards others, the world which we live and most certainly from our creator.
