I know the following sounds crazy, but it makes sense if you think hard about it.
The odds of rolling a 7 with two dice are:
6 to 1. That is calculated by taking the total combinations of the dice (36) / the number of ways to make a 7 (6).
How fast this happens depends on how fast the dice are rolled.
The odds of life happening are:
The total combinations of elements in the universe / the total number of elements necessary to make life.
It took 2 billion years for this to happen on Earth
Check out Life on Earth for more information on how life came about on Earth.
The odds of your life happening are:
The Odds of You Happening = The Total Combinations of life / The Number of Ways to Make You.
It took 8 billion years for your combination to come up.
The odds are that'll you'll come back to life after you die 
simply because it has happened once in 8 billion years.
Since nature was created from scratch 8 billion years ago, the odds of our re-creation shouldn't take as long the next time around.
So there...I've said it. I know this all sounds profound, but numbers do not lie.
Math is truth. It is the language of nature.
If you can't figure things out for yourself, then you'll have to take what others say on faith.
And faith is a symptom of laziness.
