In recent years there has been a high volume of UFO sightings around the world. Since everyone nowadays is armed with a smartphone or video camera, evidence of unidentified flying objects have been immediately uploaded onto the internet. I have my own theory! Internet shopping!! You can’t do better than shop on Amazon and eBay, and aliens know this. Ordering bargains from outer space, they enter Earth’s atmosphere in order to take up the option of ‘click & collect’. And why not?
