Living things on other earth like planets.

I think I underestimated Pro. He came up with some good answers. Let's see what I can do about this.Rebuttal:Pro's sources;Pro has presented 3 sources. I'll analyze them.Source 1; It is "10 reasons to believe aliens exist". In debates, you should never let the source do the talking. The point of sources is to prove your points right, not make the sources an argument. I'm honestly not an expert on this subject, but I'm pretty sure you have to explain the sources. Anyways, so do I refute the source? Eh, 1,000 characters. I can do it.Debunking source 1;"The Big Bang happened around 10-20 billion years ago, while the Earth is approximately 4.6 billion years old [1]. If we compare the length of time between these two events to that between two of our birthdays, we will realize that it is actually quite a huge amount of time."This is circumstantial. How can we be certain there are aliens out there just because the Universe is old?"With so much heat from billions of stars in the universe, isn't it very much possible that similar kinds of chemical reactions take place in distant galaxies? Is it not likely that there could be at least ONE such chemical reaction occurring by accident?" This is the Fallacy of Composition. It's claiming that living things are made of chemicals, therefore the chemicals are alive. Here's an analogy:An elephant is made of atoms. Atoms are tiny. Does this mean the elephant is tiny? Of course not! Elephants are huge! Thus, the source's logic falls."Water is one of the by-products of star formation [4]. And with a star born every 0.0002 seconds" Water forms stars?This source says something a bit peculiar. "The gas and dust that flows out of star nurseries contains clouds of hydrogen (H) and oxygen (O) that react together to form water (H2O)." Stars are not exactly made from already existing water. Hydrogen and Oxygen clouds react to form H2O. It's not like H2O will form, and be there long enough for a planet to form next to it. [See source 1]"Picture a distant planet where lightning is as common as McDonald's is on Earth. With just the right conditions, life may have already dawned there thousands of years ago." So lightning = life? It does also say that certain chemicals, when zapped, create amino acids. I guess this makes sense. But how do we know a planet has the right things to even create amino acids; certain chemicals, and a stormy atmosphere?Let's not get distracted by a lone source. On to the next!Source 2;Talks about UFO sightings. I've already said these people could either be mistaken, or lying. Then, ancient writing. Could very well just be a religion. 3rd, a UFO crashed in Area 51. Me personally, I'm wondering the credibility, since it's a flying saucer, and that's a bit cliché. It could very well be a hoax. If Pro wants me to address specific points, just tell me them!Source 3;So this is a conspiracy theory. A guy claims he saw some secret documents in Britain. 1, how do we know this guy is trustworthy? 2, why is Britain even hiding aliens? They'd be famous!Pro's defense;"For an example, the planet could get energy from sunlight. The planet could maybe be like a solar panel." Oh? And what might this sunlight be converted into? And how would the planet go about transforming the energy, exactly? Review you response, and think about what my next question could be, and answer my question before I ask it."Like the same, the planet's life could have formed there or came from somewhere else." So the life could start from cells, then possibly evolved into more complex beings. It's good that you did research. Now we need to answer this question: What are these cells feeding off of? We will stick to Pro's absorption theory as the explanation, but he just needs to fill in all the gaps.Argument:Pro's Burden of Proof:Pro only has 1 round remaining to fulfill his burden. I'd have to say he is a good debater; an actual one. Not like all of those purple circles that abandon the site day 1. There is but two things Pro must do: 1: Show that it is possible that alien life could exist2: Actually proving they exist.Pro's theory on absorbing energy from their planet allows a simple cell to thrive, but he must expand on this theory. How does the sunlight become edible material? This question must be sufficiently answered.But then, he actually has to prove this theory is true in a planet. When arguing that alien life exists, theories won't do. You must confirm these theories, turning them into fact. Of course, he can abandon the theory altogether, and suggest there's a planet incredibly similar to Earth. Of course, he still must prove this to be true.Final Thoughts:Now that we've reviewed the burden Pro must handle, we see just what trouble he's in. Good luck. That's all I have to say; Good luck.
