Oldest Human Footprint...We know this how?

1.5 million years ago is a long time. In fact, you can't even count that high. In fact, it's so long ago that Carbon 14 has decayed at different rates since then.

So why am I supposed to believe this "oldest human footprint" is 1,500,000 years old?

The article completely glosses over anything resembling science, and simply asks us to believe on faith. As a natural doubter, I require--nay, I DEMAND--more in a news story.

Now tell me we're only a couple trillion in debt. Now show me how we're not much farther in debt. I require more information. The problem is, nobody knows how much government spends on anything.
