There is Extraterrestrial Life Beyond Earth

I guess I'll accept his renouncement that Wikipedia cannot be used, although I heartily disagree, but if my opponent desires that, then I'll go ahead and stop citing Wikipedia. PRO starts off by arguing that ET life does not have to be intelligent, stating that simple things such as cells can be determined as life. From a biological standpoint, this is true, but for all realistic terms of evidence, cells have NOT been discovered on other planets that pinpoint the discovery of life. I would like to say that all life is composed of cells, at least the life we humans come to know of. Who knows what other fundamental properties of the universe aliens follow? For them, life could be spaghetti sauce. Also, just because there are cells does not mean that life WILL occur. Life-enabling molecules were discovered near the Orion nebula, but these are only basic building blocks, they will need to assimilate in order to form "life," and that is unlikely to happen any time in the near future, just think of how long it took for the first living organisms (or bacteria) to appear on Earth. Now, when PRO says that "where there is water, there is life" I would also like to concur. Water is necessary for all life, that is a given. But where this is water does NOT mean life will suddenly appear. There must be other necessary components, such as amino acids, proteins, etc. for life to form. Also, oxygen must be a factor for life. HOWEVER, some organisms, most commonly bacteria, can live without the presence of bacteria; in fact, they die from being near bacteria. For all sake of argument, water contains oxygen molecules. I expect PRO to know this as well as anyone who passed basic science courses. So, why is it that humans can't breathe in water, which contains oxygen? The key is evolution. Fills have gills, which allow them to breathe. Humans do not have gills. When we think of extra terrestrial life, we think of green blobs, or "The Grays. " In fact, we have never seen extra terrestrial life, we can only assume, we do not know if they can use the water and oxygen to sustain life. Therefore, even if water is found this does not immediately conclude the premise of life, meaning life is yet again another POSSIBILITY. To wrap this all up, life has NOT been found on Mars, only water, and this is water that froze over possibly millions of years ago and is not sustainable for the development of life. Also, I am not sure what you are implying with the methane gas and the atmosphere thing. Methane gas is present in Mars's atmosphere, yes, but what does this prove? Nothing, except that life is yet again another POSSIBILITY. Now, to go back on my first argument, and PRO's first statement which was "There is extraterrestrial life beyond Earth. " I do not think this is possible, therefore the burden of proof is for PRO to prove conclusively that there is in fact extraterrestrial life outside of Earth, not just sources or possibilities of there being life. Regarding the the UFO sightings and such; this is highly controversial material and cannot be used to provide any sort of accurate evidence. The media over-sensationalizes everything, their job is to report on findings, not document the accuracy of such findings. Even still, many conspiracy theories have arisen over the past years based on the government's "cover-up" of such details. This is complete BS IMO, as none of these sightings have proven ET life, again, the UFOs could be the Flying Spaghetti Monster's siblings coming down to greet us. The testimonies are all highly-opinionated, and each and every single one of their primary accounts differ greatly, none of them recall seeing the exact same details, therefore this leads to many plausible explanations, most of which are valid scientific explanations, not explanations given by firsthand sources who probably are doing it for the money and attention anyways. As for the "ET law," this should be enough to disprove that: . http://www.snopes.com... PRO concludes his argument by saying that "we have only scratched the surface of the Universe. " Hypothetically speaking, we have access to the entire universe through thought experimentation and visualization through external senses. Realistically and physically speaking, it is true that we cannot travel beyond our own solar system. But then again, if ET life is abundant, why have we not held contact with them or have evidence of their surroundings? You would think ET life would be much more intelligent than our own kind, seeing as how Earth is pretty young compared to the cosmological realm.
