Just watched one of those TV Programmes about the End of the Dinosaurs - caused by an 'Alien' Asteroid - it got me thinking, I wonder if it was, an "Alien" asteroid and sent with 'deliberate' intent, by those (most of us) have yet to know? (Cue Theme from the X-Files)
I think you mean starship troopers :2thumbsup: https://www.youtube.com/watch?v=aiXP5d3M5XM"]Russian Meteorite Explosion/Starship Troopers Theory! - YouTube hotwater
Not that the wiped out by asteroid theory isn't plausible (unlike an asteroid that would be deliberately send by aliens) but I think it is wise indeed to not take that theory for a 100% fact.
