2400 year old Mayan hieroglyphics discovered

Our history books and everything we were taught about human history appear to be rewritten with each new archaeological discovery. I just read about the "Earliest Mayan writing found beneath pyramid" posted at CNN this evening (1/5/2006). This new discovery is roughly 300-400 years older than the oldest known Mayan hieroglyphics. I've always believed that human civilization is significantly older than what we were taught in our history classes.

I keep following these archaeological discoveries year after year and the age of human civilization and the capabilities of the ancients keeps growing. One day, the history books will be rewritten and put the ancients on their appropriate pedestals of accomplishment. For now, these discoveries and findings just continue.
