The world is doomed

Many things are likely doomed, but as "only facts count as arguments," the world being doomed is far from a fact; anything which is a fact instead of a theory, should easily hold up to rebuttal."If there is no Earth for humans to live on, then humans are also doomed. So if the World is doomed, so is humanity."By this I take pro's definition of The World, to be the planet earth; I will however make secondary points in favor of humanity to maintain a sense of relevance to us; finally I shall attack the sources.Rebuttals:1. Nuclear Warfare."All it would take is one to get into the wrong hands, or even go off by accident, to start a chain of nuclear strikes as a'defense' to the first one." In summery a lot of hypotheticals, when he wrote the rule about using only facts. Even his source points out how hard it is for nuclear weapon to go off by any means other than their own control (his source lists many accidents, even armed bomber collisions with zero accidental nuclear detonations...). Pro proposes a Dr Strangelove [2] situation, where there's a doomsday device which will destroy the world if a nuke goes off in the wrong area, and there are zero fail safes on it. This is getting into the area of absurdity. Not to mention all the lost nuclear weapons are useless, unless the Neutron Generators (a component needed to cause the chain reaction) are replaced every few years [3]. The World: The earth is 4.5 billion years old, with a surface area of 197 million square miles, and is the most dense planet in our solar system. It has withstood worse conditions than mere nuclear wars. Humanity: The Japanese are the only nation which has suffered nuclear attacks, thus as experts on the subject. With the highest life expectancy of any nation, and 128-million people living on their island [4], it's safe to say the threat of nuclear weapons outright wiping us out is greatly exaggerated. Source: Pro provided an article written by journalist Benjamin Maack, a freelance writer for such informative titles as FHM and Fit For Fun, and editor of the video game magazine GEE [5]. Clearly only an entertainment writer, not a reputable source on the apocalypse. 2. Meteors and Asteroids.Pro proposes Deep Impact [6], a movie rated 53% lower on Rotten Tomatoes than the last one. The World: Not a threat to the earth. A truly massive one struck 65 million years ago, and life went on; kind of how we got here [7]. Humanity: NASA (in addition to other groups) have us covered. They've searched the sky and identified the possible threats which have paths that could shift into a collision course with us. Given how slowly things move through space (in addition to how empty it is), the odds of us having less than a century notice is 1 in 1000, but even then "There will be no great hurry, and no great panic. ... It probably would take only a small impulse (chemical rockets, or perhaps mass drivers) to divert it from a threatening path" [8]. Source: From pro "Even if we used nukes to try to blow the thing up, it would only result in breaking it apart and still having huge chunks hit Earth with major destruction." Major destruction, not doom. Plus his own source disagrees with him: "NASA tested four nuclear scenarios: a surface explosion, a delayed surface explosion, a subsurface explosion and a standoff explosion (where the bomb doesn't come into contact with the asteroid). The surface and subsurface explosions are the most effective, but there's a good chance of splitting the asteroid. In the end, the space agency determined that a series of standoff nuclear explosions would be the most effective way to deflect an asteroid headed for Earth." 3. Disease."Even if it's 'somewhat possible', it's not 'impossible.'" Somewhat does not even come close to a fact, thus this section is again going against pro's own rule. The World: The Earth is a clean planet, that would not go within 365 million miles of a loose planet like Jupiter. It has no known risk of catching any disease (nor are planets known to). Humanity: Strange as it sounds, diseases actually strengthen the human race. The Antonine Plague decimated Rome, and today we call it Measles. The worst disease we've ever known was the Black Death, and people surviving it is now connected to HIV immunity [9]. We worry about diseases for reasons of self preservation and compassion, yet the human race itself is in no danger. Sources: No source to counter. 4. Our Galaxy will collide with the Andromeda galaxy."This will no doubt cause a catastrophe to the world." Unless you've read pro's source, which states all that will happen to us is a "spectacular evolution of the night sky," into something like this: The World: No threat expected. Humanity: No threat expected. Source: Pro's source claims "The great galactic union isn't expected to result in the destruction of Earth, the Sun, or any other planet in the solar system. In fact, no stars whatsoever are expected to collide becauase they are so far apart within each system." Which clearly favors the world not being doomed. 5. The End of the Sun."The Sun will cause all life on Earth to no longer exist." Such a long time from now the relevance is questionable. The World: Like in all of the above, the earth will keep going. Yes the surface will be blasted, but after it all here's what pro's source thinks the earth will look like. Humanity: In the last century alone human progress has been astoundingly fast, and seems to be accelerating [10]. Yet even at the median level recorded over the last 2000 years, 3,500,000,000 years gives us plenty of time to adapt in ways we cannot begin to predict. However looking on a much shorter time frame; according to Stephen Hawking, colonizing distant solar systems is highly feasible "the main challenges won't be technical. The first will be financial. ... For the society that made it, there would be little payback: they'd never see it again" [11, video link]. Thus if there is ever a threat to our presence on the planet, there will be the motivation to ignore short term factors of money and flee. Abandoning the Earth (which will take care of itself just fine without us) is a valid option for humanity. Source: Pro's source for the sun will die is Ron Miller, is an artist with a talented imagination. His website has some very interesting fantasy women on it, including naked-tiger-striped-furry-pirate-babes (NSFW, thus shall not be linked). Pro opted to begin his argument in the final round, forgoing defense of his points.His numerous arguments are unstable at best, and his sources have all been countered (some of them flipped to my favor). Yes it is clear the world and humanity will face problems in the future, yet mere problems and outright doom are not the same.
