What no brainer opportunity? Having to accept the "Word of God" based on 100% no brainer (blind) faith in someone's "Revealed" hearsay? It makes no sense that God would give man the unequaled power of reason, and then expect us not to use it in such a critical decision.
Only one problem with reincarnation, how can we learn from our past or correct our mistakes if we don't remember them or even the individual we once were? "Feelings" of a past life are as unsubstantiated as the other feelings people have that they "communicate" with God. And no one can tell me I'm not listening, or can't hear because I don't have faith or whatever ephemeral quality I was apparently not endowed with. I trust (have faith) in my demonstrated, inherent ability to reason, and have learned to live with the doubt. By all appearances, this is our one shot, make the most of it instead of procrastinating to the next life.
Past lives can be accessed through meditation, dreams and much more. There is, IMO, far more than this one life to learn from. And yes, I believe I speak from experience.
