"For many years, it was thought that the Clovis people were the first humans to populate North America, about 13,000 years ago."

But all that has changed, due to the discovery of a mastodon rib with a bone point skewed in it.  The fossils were discovered in the late 1970s at the dig site, Manis, near Sequim, Washington.  Dr. Carl Gustafson, an archaeologist at Washington State University, theorized that the fossil was about 14,000 years old.  Although many scientists did not believe him then, but technology has advanced and he, along with other scientists, now uses mass spectrometry to pinpoint the date of of the bone.  They also used a CT to look inside then mastodon's bone, confirming that the bone lodged inside the mastodon was a hunting weapon.  The weapon was more than 10 inches long and sharpened.

Science is really advancing these days.  We came from sticks and stones, then to metals.  From the metals, we then mix them to form stronger metals, with enhanced qualities.  We can even make new metals and synthesize them with non-metals, giving the product a truly unique quality.  Now, we are beginning to dive in the realm of subatomic particles, who knows what we may do next.  The point that I'm trying to address is that everything will improve, even if it's for the worst. just look at the last century, in that time, scientific knowledge has tripled, maybe even quadrupled. One minute we're launching shuttles into space, and the next minute, we have men living in space.  History is being written right now, and once we've passed away, our future generations would look back and see us, making these discoveries.
