[ WP ] You return from a space mission to find that human life on Earth is non-existent . What has happened ?

It had been five months since the last transmission had been received from Earth. Nikoli Alexander had made desperate repairs to the comms unit. Eventually, frustrated, he had taken it apart and rebuilt it. When he had turned it back on something much worse than static had come out. It sounded like the constant scream of a creature in severe agony. He had turned the comms unit off again. 
 
 His heart had sank at the thought of being totally alone for five more months. He had only agreed to pilot the tiny one man science vessel, the Soyuz, in return for a weekly transmission to the craft from his wife and daughter. He had wept. 
 
 As Earth came closer into view he knew it was n't his comms unit that had malfunctioned. `` Dear Lord'' he said out loud in a thick Russian tongue. He could make out the shape of North America. He could not however see any lights. From this distance he should be able to make out an effervescent glow over a large part of the USA but there was only green. As the globe rotated he saw no lights in Asia or Europe. 
 
 He attempted to rationalise `` Perhaps... perhaps a massive electro magnetic pulse has taken out all computers and lights''. He had months ago begun talking to himself - it kept him sane. 
 
 If he had been able to turn around and head else where he might have. However there were only a few days of air left and very little food. He began the re-entry process. 
 
 A tiny pod floated alone in the Atlantic. Usually it would have been found instantly by the team at Roscosmos or NASA, and the crew would have been given a heroes welcome. For Nikoli Alexander this was not the case. He had to sit tight in the cramped pod and wait for the tide to expel him onto land. He had packed the remaining rations from the Soyuz but found himself running low. During the nights he would open the the lid of the pod and watch the stars, attempting to work out which direction it was floating. He could make out Cassiopeia to the east and kept track of it. He believed he would end up in Central America - possibly Mexico. 
 
 The pod hit the rocks with a thud. Nikoli awoke from a deep slumber. He had not eaten in three days and had little energy for anything other than sleep. He opened the pod and looked around. The pod had gotten stuck between two large rocks jutting out of the sea - he was lucky they had n't pierced the hull. About a mile away, beneath the bleak grey sky he could see a shore. It was a small sandy beach. For the first time in many months he allowed himself a smile. 
 
 Adrenaline pumping, Nikoli prepared to slide into the water to begin the swim, when he saw something move on the shore. `` Hello!'' he shouted. It moved again. What the hell was it? Too fast to be a human. He heard a familiar blood curdling scream and saw more creatures dart onto the beach.
