Sentient, technological beings exist only on earth

From my contention it is clear I am not speaking of humans so I need not respond to my opponent’s rebuttal. My opponent has falsely interpreted my rebuttal. When I say there are “millions of possibilities why” I mean that there are millions of possibilities why alien life forms haven’t altered their galaxy! Perhaps they aren’t that advanced, perhaps they don’t have the resources, perhaps they don’t want to, perhaps some form of religion has prevented them, there are possibly millions of possibilities! Planets capable of harbouring our form of life have existed for ca. 10 billion years. Earth has been capable of harbouring sentient TECHNOLOGICAL life for 10 billion years. Yet we have only existed for 3000. We have been possible for 10 billion, yet why haven’t we been around for 10 billion? First, the underlined quote is a simple restatement of my opponents earlier comments about cost and therefore not a rebuttal. Umm, yes it is. It isn’t at all a restatement; it is evidence showing that Space research has been shut down because of cost. Second, my point was to show that expensive technologies have become cheaper, simpler and better with time. How can space exploration become better and cheaper and simpler if NASA is shut down permanently? All of my opponents rebuttals to the solar sail example are answered in the above document. I’m sorry, but I get a 404 error when opening the site. VOTERS, PLEASE TRY TO OPEN THE SITE. However, I do not understand why my opponent wouldn’t merely post the rebuttal. As the question has not been answered as the link cannot be opened, my refutation stands. As you can see in the above documents Which I cannot open. I have provided sources (that can be opened) showing that solar sails can barely reach 1/10000th of light speed. Clearly, it is impossible to achieve light speed before we all die. I asked you a question. Which I had already answered. There are millions of reasons why, some I have listed above. You have placed words in my mouth. I have never said that there are millions of other species out there. I am happy to see you have scaled back your argument to one species per 100 billion solar systems. My opponent CONTINUES TO PLACE WORDS IN MY MOUTH. I never said one per 100 billion, I said one per galaxy. My opponent assumes I have said something I have not said, then twists what I have said. There are 100 billion visible galaxies Visible now. The closest magnetic cloud is 25 000 light years away. What we see now happened 25 000 years ago. So if someone out there is manipulating their galaxy, we will not know for thousands and thousands and thousands of years. I have shown this above, it has not been refuted. I don’t claim this. I apologize if I implied it You have implied this, saying that life has been possible for 10 billion years, that means there have been 10 billion years for something to reorganize their galaxy. It is possible that other species may exist but have chosen not to manipulate their galaxies. Thank you for conceding the point which I have mentioned many a time before. But exploration and tampering are human nature. Other species out there aren’t necessarily human. Specious. This isn’t adequate refutation as no evidence has been supplied There are only 2 of the many unlikely events that would have to occur to produce humans. Yet this is happening in front of our eyes on Mars (e. g. the bacteria found there! !) I agree. .. just not sentient, technological life. Give them time and they’ll evolve, just like us.
