THB: Extraterrestrial life exists

Now assuming from the website you have cited in the first point of your debate and the stigma that surrounds the title of this debate, I am taking the standpoint here that we are discussing the pints of view that intelligent life could exist somewhere in the Universe, and the answer to this question is that the chances of this happening are in fact very unlikely. Now of course there are Government institutions such as SETI set up and designed for this search of alien neighbors which may possess the intelligence required to communicate with the human species. However, outside of our solar system, it is extremely difficult to identify where this alien life could settle. Key astronomers have pointed out planets in other systems, light years away, which may possess the ability of possessing alien life. However to manage and sustain life, there must be key points which must be addressed in an atmosphere and planet's surface, in order for life to flourish. According to the Drake equation, there are an estimated 60 billion different planets in our universe that could possibly have the potential of supporting some sort of extraterrestrial life. Now this does seem like a significant amount but every single thing that we hope to understand must be taken in relation to a key context. Now within our known universe there are approximately 100 billion galaxies. Within the Milky way there are 100 billion estimated stars, and assuming there are around 8 planets within a solar system, we can assume that there are 800 billion planets within our galaxy alone. using the approximate 100 billion galaxies, we can use mathematics to calculate that there are around 80000000000000000000000 planets within our known universe. To take the idea of this and divide it by the number of planets in which Drake's equation predicts can hold alien life, we see that only 0.00000000000075% of the planets within the know universe could possibly have the mechanisms support alien life. The chances that life came to the way it did on Earth has a mathematical probability incredibly low also. Taking this into account we can see that if we had one single bacteria, that would randomly be allocated to a planet. If it were to land on the planet that could support life, it would begin to multiply to form multi-celled organisms and continue to grow until life prospered. The bacteria would have the very long percentage chance which I said of reaching a planet which could support it. On top of this the percentage would lower as to whether the bacteria could in fact multiply into more organisms and finally, the chances go further down because of the fact that the planet may not be hospitable for the organisms which the bacteria evolves into. However, there is this constant argument that it happened on Earth and it did. We somehow, went through all of the chances and now we are here debating this topic. However, seeing our chances of existing as this percentage is hard enough to comprehend, but to believe that life similar to us, that can build major civilisations is almost beyond contemplation. The chances of winning the lottery are one in 14 million. The chances of being life on another Goldilocks planet would be the equivalent of winning the lottery for every single day for a whole week. Whilst the mathematics show it is possible, we can see that this applies to the state of the Earth. In order to see other planets, this means that you would have to take the equivalent of winning the lottery 14 days in a row. Again, the mathematics show that it is possible, but is it likely, the answer is a very stern no.
