This is, of course, one of the most played out topic in the history of human-kind.

Personally, I don't believe in it.
The idea that humans came from the same ancestors as apes and monkeys and whatnot bothers me.
You can post as many facts as you like, but faith is all I have.

I'd like to believe that there is more to life after we all die, who knows, maybe there isn't but it doesn't hurt to try.

This is actually a question that has perplexed me once I became familiar w/ Floridian geography as a kid. Jacksonville actually has the largest population out of all the cities in FL. Does that mean that Miami has fewer people 'cause of all the suburbs in it's metro area, e.g. W. Palm Beach, Hialeah, Ft. Lauderdale? Does J'Ville have few suburbs? & what is the economic & geographical significance of the northeastern FL city? If I'm also 2 understand, Jacksonville is actually a few miles from the coast & I think the St. John's River empties there. I'd like some good info on comparisons between Jacksonville & Miami.
