THB: Extraterrestrial life exists

I apologise for the mistake made in the round one comments, this is down to my error of not reading the rules of the debate with clear precision. However, my opponent has also made a clear error within their first argument here. The party arguing for the motion, and myself also in my first, disregarded statement, have debated an entirely different motion to the one outlined here. We have both argued for the motion of "Could Alien life exist". Using the mathematical probability here anyone is able to say that it could exist without any form of scientific proof. Using this same argument we can say without certainty that God exists, flying saucers exist, and the great spaghetti monster of the east could exist, purely for the fact, that the maths cannot be disproved to 100% certainty. The real point in which we are debating is "does alien life exist", through the clear title of "This House Believes Extraterrestrial life exists". If we argued could it exist, I would say yes, but "does it exist" is entirely different. Every point outlined in your Round 2 argument clearly states that you believe that alien life could exist, but you have in no way provided reasonable evidence for your belief that it does exist. To determine whether something exists with 100% certainty, we must be provided with irrefutable evidence for the existence of the object in question, and I am sorry to say that there is no such evidence that can be provided for the existence of Extraterrestrials. There is however, suggested evidence for their existence but these can be simply dismissed with a few key arguments. There are 3 clear arguments given as to why alien life exists through the evidence. The first is cave paintings, found in caves throughout the world. Primarily found in Egyptian hieroglyphs, these depictions show strange looking men, with large heads, large eyes, matching many descriptions by eye-witnesses of what they believe to be aliens. Caves found in India have also been suggested to show these same things but upon closer inspection, it is clear to see that these may just be artistic interpretations of humans and maybe even deities that these people believed in. If we are to believe that Ancient peoples interacted with aliens simply because they drew them on their walls, we must believe in all deities ever drawn by the ancients, as they must have encountered them too. (See source 1 for Indian cave paintings). Secondly we look at the evidence of eye-witness testimony, of people who have seen aliens, UFO's and even report to have been abducted by these beings. We cannot take simple eye-witness testimony as argument that something must exist, because a select few people have seen it. Again, in this same way we would have to believe in the existence of ghosts, Sasquatches, werewolves, vampires, etc. all because a select few individuals report to have seen them. Eye witness testimony is also something which can also be largely skewed by individual factors. Tests done by Loftus and Palmer have shown that peoples reporting of an incident can be skewed based upon leading questions performed by the interviewer. They found that people witnessing a car crash, reported the cars as going at a faster speed, when the verb used to describe the incident was more violent, escalating from contacted to smashed. (See source 2 for article publication). When looking at these interviews, it is clear to see major biases in the research which skew results. There exists investigator biases, making individuals want to give answers to help the researcher, many hoaxes relating to the issue, the fact that in many cases of hypnosis interviews, many of the individuals had read at least one or two more books relating to the concept of abduction. (See source 3 for data). Finally we come to video evidence and pictorial evidence for the existence of aliens and UFO's. Firstly we come to the videos of UFO's, easily faked videos usually lasting approximately 30 seconds to 1 minute. Shaky footage of a piece of metal in the sky is not concrete evidence for the existence of alien life. Similarly, the movement of random lights in the sky is not evidence either. The definition of UFO is "Unidentified flying object", meaning that the objects in this videos have the possibility to be anything without being craft piloted by alien life. If something is classed as "unidentified" you cannot claim it to be something without clear and justified evidence. Finally, we come to evidence from outer space, evidence which does not exist. We have found no evidence, let alone concrete evidence, of any life beyond our planet Earth. Despite rigorous searching and studies, there has not been any evidence for Extraterrestrial activity within the known universe. Using mathematics only proves that something may exist. Until there is solid and published evidence that alien life exists and can prove beyond a reason of a doubt that other claims are false, then nobody can state that alien life exists. To justify any claim you need evidence, and since there is no evidence for alien life to this date, the claim that there is, is unjustified and until I am disproven, it is false.
