to natural phil.,,hi the first question you ask revolves around "intelligent design" and it has nothing to do with the complexity of the universe per se. It has to do with logic. Simply put ,if you find a watch ,you marvel at it's mechanisms,now the watch either came to be randomly, or there was a watchmaker . It is self evident tahat these parts did not randomly fly together magicaly,so there must have been a watchmaker.There is an old philosophical saying that what you can say of a simple object ,by extension you can say of a more complex object. So it is by extension that we say ,,the universe is greatly more complex,,and if the simpler obj.,the watch had a watchmaker,,then it wld be reasonable to say ,the universe had a universe maker. Simple. Your second question operates on the premise "mary was a sinner ",,most christians do not belive this ,,she was regarded as sinless. Your last quiry is the old test. states an eye for an eye,,yes but christ said he came to deatroy the old law [old test,he was the fulfilment of the old prophesies.....hahrley dav.
