It is the way it is because if it wasn't the way it is you wouldn't be here asking why it is the way it is.
What I mean to say is that we are looking back on everything that has happened in the entirety of the universe and saying "wow! it's really unlikely for things to turn out this way without any kind of guidance", and for some people this is enough to conclude that there must have been some kind of guidance.
But we must remember that things have to turn out somehow, no matter how unlikely it is to get a specific 6 numbers in the lottery, if we were the 6 numbers that did appear, we would be like "wow! it's really unlikely for things to turn out this way without any kind of guidance". But it happened. There is no why about it. It's just the way things are and there's no intelligence behind the universe, there's nothing that decides how or why. It just is the way it is, no matter how unlikely that would have been at the very beginning, luck turned out to make the world the way it is today.
Does that help? (I don't think it does:))
