The Nature of the Universe

If a tree falls in the woods and there's nobody around to hear it, does it make a sound?

Okay, what if a universe exists and then disintegrates , but doesn't produce anything that can be observed? Did it exist?

Our universe is basically defined by several constants and fundamental laws. Change them, and atoms don't stick together, or the universe doesn't expand, or matter doesn't form, or whatever. So isn't it lucky that the universe just happened to have the perfect conditions for life?

No. There have been an infinite number of universes that failed to produce life (or that produced life but didn't last long enough for us to find). Our universe is a product of the Law of Averages. Hail Eris!
