You claim that successful behaviors don't lead to success, right?
Here is the problem as I see it... you're now trying to somehow equate "successful behavior" with this "universal morality" you claimed. There is no correlation. Successful behavior doesn't have to be necessarily moral. Moral behavior doesn't have to necessarily be successful. A drug lord can be all kinds of successful but what he does is highly immoral.
So, allow me to try and help your OP argument a little here.... I've been critical because I think you're not actually articulating this the right way. What you are trying to get across is not necessarily wrong it's just not as you've tried to convey it.
I am a Spiritualist. I don't belong to a religion, I don't believe in any organized religious incarnation of God. I do believe in God but my interpretation of God is Spiritual Energy. This is an unseen natural force coursing through our universe of physical reality. It is essentially what directs humans toward good and away from evil.... toward the light and away from the dark. Did it "exist" before time and space? It's inconsequential because it applies to physical reality within time and space.... it doesn't matter if it did or didn't exist. The SOURCE is Spiritual Energy and the cool thing about that is, it CAN exist beyond and before the physical... in fact, I believe that's what created the physical.
Morals are simply rules established by man, usually through spiritual understanding. There is no "universal morality" because man is flawed and incapable of establishing such a thing. Truth is never known.... we can't KNOW anything absolutely... we're humans. We can
believe we know and that is all. Billy Graham certainly believes he is going to heaven... BUT... until he dies and actually goes there, he doesn't KNOW.
