My obvious limited scientific understanding, lol, you sure got me on that one bud. Science doesn't have to have all the answers (nor does it claim to have all the answers), if it did have all the answers it wouldn't be called science and it would look an awful lot like something we like to call religion. Me not being able to give you a cause for it means absolutely nothing, I am not an astrophysicist nor is my understanding of quantum mechanics great enough to explain to you in the simplest terms why this is all possible. Arguments are easy when all you have to say is that your all-powerful, omniscient god who has always existed and will always exist is responsible for 100% of everything that ever was and will be when you don't have to provide any evidence whatsoever confirming the existence of such an entity. And saying the Bible is evidence is you A) wholeheartedly trusting a 2000 year old game of telephone in which the original text was translated and edited countless times and B) employing circular logic. Good day.
