There is a major problem with with secular humanism because prior hominids, those of which were incapable of speech, and by cause and effect, religion, were still burying their dead and living in groups with each other. Which demonstrates that we are definitely capable of morality and social bonding without religious belief.
Name one moral thing that a Christian can do better than an Atheist.
Morality is socially influence and dependent on a different variety of factors. What is moral in our society may be completely immoral in another and therefore; there is no universal acceptance for what ought to be. It is a natural progression that is socially influenced to benefit the existence of whatever is trying to survive. There is no reason to change it into a convoluted philosophy that is completely independent of social norms, this simply isn't the case. If it were, than morality, in all regards, should be universally accepted on every level, but it isn't.
If there was an individual who was capable of demonstrating that miracles do happen, don't you believe that it would have occurred already? It hasn't. That is as simple as it can be stated. Therefore my assertion that nobody is capable of doing this, simply because nobody has been able to yet, isn't grandiose or misleading, it is actually very accurate and is completely dependent on observation.
Transcendent meaning may or may not exist, and our only way to find out will be via scientific means, not religious beliefs.
