Reincarnation - a truth or myth

Today I feel eternally blessed and feel genuinely happy inside, despite of the problems on my pheriphery...Reason - Two of the people who touch my life in more ways than one make it worth living were born today...And I want to thank them so much for being a part of my life...All my sincerest wishes go to them both and may they be blessed eternally.Now to the topic - Which again sent my grey cells in a tizzy and started me thinking...The discussion started off with my better half as usual and as expected, we were on completely opposite sides of the fence.He didn't believe at all in this enigma of karma and punarjanam whereas I was adamant that one's deeds good or bad in the past births are responsible for mankind's bliss or miseries respectively in this lifetime. I can quote numerous examples which come popping in the media every now and then about kids who can give full details of their previous lives, name people they have never met or tell about places which they have never visited. And there is enough evidence to substantiate such findings...So I'm convinced that reincarnation is certainly a reality. Now comes the issue of whether every living being is a mere puppet and comes to life only to experience his or her past deeds and cannot control his life fully with his actions or inactions. It cannot be a mere chance that mental illness strikes some people and they lose control of their mind, body and ultimately of their lives though they haven't done any considerable harm to anyone but on the other hand, murderers, sinners and corrupt politicians keep on living luxurious lives. The argument which I really liked from my counterpart to this theory was : He asked me to name one person who doesn't have any sorrows in life and I couldn't. So according to my theory then, everyone has committed sins in the past since nobody is without miseries in life which was difficult to counter argue.To put forward my point, I told him why only some people become rich, famous and successful in their craft that they get accolades from whole world whereas other humans clean filth all their life to which he answered that These bigwigs have their share of problems in life.So according to my theory then, everyone has committed sins in the past since nobody is without miseries in life. Maybe the magnitude of the sins or misdeeds done in the previous births amounts to the miseries one faces in this lifetime.Life itself is a vicious circle in which everyone comes to experience his or her share of joys and sorrows.Whatever name we give to it - Destiny, previous deeds or something else, there is an external force which is guiding us all. How does it explain otherwise the different awareness and maturity levels of individuals. The ones who remain so engrossed in vyasanas and the futilities and the others who attain vast knowledge of the upnisads and vedas and not only just preach but also apply those ways and virtues in leading their lives. So the question still remains open ended and for you guys to introspect - Is the theory of past karmas just there to instill fear in humans so that they steer clear of all vices and be humane to their fellows.
