One cannot deal with origins apart from faith. Observers were not there (except the God of the Universe)
Ah. So that's why OJ wasn't convicted. No eye-witnesses.
By your own "rule", you can't determine whether a god made the universe, because none of us were there to watch it.
In any case, the childish assertion that science requires "an observer" on the scene (or that anything determined without an eyewitness is nothing more than "faith") is laughably wrong.
Watch any of the plethora of "crime scene investigation" TV dramas which are running this year, if you want a taste -- they're all about how science is used to determine what happened at a crime scene beyond a shadow of a doubt, BASED ON EVIDENCE, and WITHOUT having the luxury of having a witness (or the killer) simply write a narrative report of the events.
Please, before you attempt to critique science -- learn something about how it works.
