Was doing some digging and i saw this, these theories, well i won’t call them theories, heck whatever they are get me all tingle inside, this will probably scare some people but whatever. It amazes me how they left out some pretty good ones like:

• Overpopulation
• Global War
• Religious Theories, Mark of the beast etc

If you really think about it, human life as we know it can be eradicated quite easily.
