The Fantastic and Odd

I haven't yet researched to find out if any of this is true, but it's making me marvel at how fantastic the world can be. From sandaled footprints fossilized in 110 million year old rocks to The Dropa Stones to sparkplugs found in 500,000 year old fossils. . . what does it mean? Has time travel been invented and we are finding evidence of messy futuristic beings? Or is all of it a big science fiction inspired hoax?
