Like with the inception of most dank memes, you might find yourself wondering, wtf. Well, good thing you have us here to describe how the strangest memes became popular; this particular meme, entitled "When Was Calcium Invented?" got its start in October when someone posted a meme to Reddit showing that someone had Googled when calcium was invented (1808, as it turns out). From there on out, dank memers have taken it upon themselves to show what life was like before the inventions of various things. All in sarcastic nature, of course.
