Wondering if Cave Men Drove Pick-Up Trucks?

Did you ever wonder how early man got around?  Well I think that pre-historic men drove Pick-Up trucks.  What?  You think I am crazy and that I slipped a cog or two?  Well now, I found proof on the Internet, and you know that everything on the Internet is true and accurate, right?  Well, this blog will be posted on the Internet and it is always true and accurate!!

OK, now how do I know that cave men drove pick-up trucks?  Well, I am not sure if it were pick-ups or cars or limousines or motorcycles or what, but what ever they drove, used spark plugs.  You see, three people (Wallace Lane, Virginia Maxey, and Mike Mikesell) were hunting for geodes in California.  They found a spark plug encased in a lump of hard clay.  This happened on this day, February 13, back in 1961 (the year I graduated from high school).

So, how did a spark plug get encased in a 500,000-year-old geode?  Give me another explanation of how it got there other than cave men drove pick-up trucks.  Or maybe visitors from another planet. . nope, they would be way more advanced than to use spark plugs.  The argument against this is that it was not found in a geode but a hardened concentration of dirt and rock, which could have formed only a few years in the past.  Now I wonder, why didn't the article tell what brand it was or what name was on the plug?  OH, that is right, they couldn't read Martian.  Now, you all don't leave your trash laying around to become a future artifact and have a great day now, you hear?
