If it satisfies you, more power to you. That doesn't satisfy me. Very little of 'science' is observed anyway. Most of it just makes me laugh.
The hard truth IMO is that there is an intelligent designer of the universe, at the very minimum.
try to study then the origin of some religions, muslim and catholic are most easy to find out, some more new also are.
but all religion is not meant for teach morals/ enforce a set of rules, its all about control, rome started to use catholic religion because was more easy to let people follow that then force then to the old religion, same witht eh old bread and blood coliseums the whole things was just a show to let people vent so tehy could keep the population under control,
monogamy was more likely invented so men could make sure the kids comming from that woman was his, hence why the older son was always the most important, he took her as a virgin so that boy would be his, after the first time unless he keep her locked there was not way to be sure anything after would be his, polygamy was just a way for powerfull men have several kids, remember polygamy in religion is always men having several woman, not woman having more then one men
btw
the hard truth is everything is chaos there is not relation on anything, everything happens, no one can control, saying there is someone controling thing is just a way to make yourself feel better and not alone, far easier to take a miserable life when you belive after this one you will get to a better place, then taking in for what it is, your life is your own only you can make it better or worse, everything who happens in your life is your fault, be by action or inaction, there is no savior and no one to guide you, you are on your own
