You have 2 choices – believe in the rock-solid most fundamental principle ever devised by science and so far never violated, that being, 'matter-energy' can neither be created nor destroyed – or you can trust in a new word – nyll – invented by, possibly just a member of the public. The above conservation law, also, automatically implies that there has ALWAYS been something (and that includes before the big bang) and that there WILL always be something. Another way to put it is that our universe did not come from 'nothing'.Has a total vaccume with nothing in exsistance been established yet? If yes then I see what your saying, something can't come from nothing, if not hmm how do you know if everything has not been organized by something we couldn't explain because our comprehention can't do so, remember the only reason we can see, hear, touch ,smell,and taste is consciousness why couldn't we be a experiment from a consciousness we could never understand?
If you prefer to believe you can get something from nothing, then any thing's possible and you don't need science for that, just magic.
