The odds on being born again?

This is not a religious question so please keep religion for another thread.
This is something that interests me purely in a `law of averages` kind of a way. The premise is this.

If we believe the big bang then everything came from nothing after the bang. Even if the big bang is not correct there was a point for all of us when we did not exist, and then through the law of averages, coincidence, natural selection, call it what you will, things came together and we were all born. At some point we will die.

So what’s to say this cycle will not happen again and is there any scientific evidence to suggest it might? Or is it a one chance only scenario?

Don’t forget that once we die time has no meaning, as it had no meaning before we were born. So many big bangs could happen, many trillion of years could pass in the blink of an eye until we are born again.

It happened once so why not multiple times? Of course we would not be aware of our previous existence so don’t go down that route please.

I would be interested in your thoughts. I like the idea that once I die I may get the chance to live again someday.
