At some point in every human's life, the three most fundamental questions about life come into everyone's mind:

1. Where did I come from?
2. Why am I here?
3. What will become of me when I die?

Atheists answer these questions by insisting that:
1. All of life came into existence entirely by random chance.
2. There is no "purpose" in life.
3. When the human body dies, that is simply the end. There is nothing beyond.

Within every human spirit, however, there is an intuitive understanding that there simply has to be a much better, more sensible explanation. (cf. Romans 1:19)
