It was 100 million years ago, when, in a flash, an alien spaceship hit the face of the planet and brought out three mysterious objects.
“We place them here, and then in three million years time, the reign of the humans will begin!” said the lead alien.
“When will we come back to get them?” asked the deputy of the aliens.
“In the year 2019 then we will start war to see how their defence has changed through time!” said the alien chief of the military.
A few million years later, the world was preparing for war against the aliens!
