Do to really believe a snake talked?!

[John V]

So you say "what then caused the universe?" Well, you cannot have only "nothing." Also, you cannot have only "something." Therefore, you can deduce that to have nothing you must also have something. Without "something", the term "nothing" makes no sense and vice versa. So there has always been a combo of both stuff and no stuff. We can see this as the vast majority of the universe contains nothing(empty space).
So imagine all the black holes in the universe over the course of time swallow all their neighbors, then each other one by one until you have one black hole containing the entire universe minus one spec of dust. This black hole is unstable and near its threshold of being to weak(even gravitationally) to hold together matter of this magnitude. So suddenly, boom, Big Bang. The process then begins all over again.
Again, this theory is to help you people realize that there are ways to explain the universe at large without ever needing "divine guidance." You are a human brain, equal in importance to the cosmos itself. Do not delude and humble yourself with iron-age fairy tales.

Yes, a cyclic model is the best hope (the only hope that I can think of) for atheists to counter the first cause argument. However, to date there's no accepted model. All proposed have serious flaws.
