Existential Threat: Your Greatest

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

This book was written with four kinds of open-minded readers in mind:

First, those who know there is no God.

Second, those who are convinced you can't know for sure.

Third, those who think it is possible, maybe even likely, there is a God. 

Finally, those who are convinced that there is a God.

Regardless of your conclusion, you will find this to be an interesting and worthwhile read.
