Certaintly complex life must be incredibly rare, if not non-existent, in our galaxy. Scientists would agree
See Makaya, it's statements like this that lead people to call you a troll. It's not just making stupid, self-evidently incorrect statements that's the problem. It's not even making such statements in direct contradiction to previous statements you've made that's the problem. It's making the same ones over and over again without ever even pretending to show any evidence of acknowledge that you've read, let alone actually understood anything anyone else has said.
Let's look at this latest one in a little more detail shall we? Starting from the end:
"Scientists would agree."
OK, first problem is that this is the exact opposite of what you've claimed previously. You've referred repeatedly to how scientists are being stupid for claiming that extra-terrestrial life could exist, yet now you are claiming that actually scientists agree with you. Secondly, you haven't even tried to show any evidence to support this. You did once almost try, on the first page of the thread, where it was conclusively shown that your huge list of four people consisted of at least two scientists who don't agree with you and one person who isn't a scientist who doesn't agree with you. Since then I'm not aware of you trying again. Both in science and in debate it's considered bad form not to provide evidence, and even worse form to continue to make assertions when your evidence has been shown not just to be lacking, but to not exist at all. Finally, it's completely wrong. A great many scientists think that ET life is probably quite common, and there are large projects set up to try to find it, and even to broadcast our location and information about ourselves to them. Of course, those scientists may be wrong, but that doesn't mean they don't exist.
"Certaintly"
Very little can ever be known for certain. When it comes to something like life, that very little becomes even less. There is a huge amount we don't understand about Earth life, a huge amount we don't know about the Earth itself, and even more that we don't know about the history of the two. As for other planets, we barely know anything about the ones just in this solar system. We've seen a few rocks from the Moon and we've taken a few pictures of the surfaces of the closer ones. We can speculate and make educated guesses about the probabilities of things, but no scientist would ever claim to be absolutely certain of anything about this subject.
Also, there are too many "t"s in that word. I'll leave it as an exercise to the reader to work out how many there should be.
"complex life must be incredibly rare"
There's that "must" again. When engaging in debate, it's generally accepted that it's best to be brief. You might run the risk of repeating yourself if you repeat the same words or implications because you run the risk of repeating yourself. Having said "certainly" already, the word "must" is completely extraneous and merely serves to make the sentence unnecessarily long-winded.
Grammar aside, you are making an assertion. Regardless of whether you view this as an exercise in debate or a discussion about science, you need to both define your terms and support your assertions. I've already dealt with supporting your claims, so here I'll just stick with the former. The problem here is with "rare" and "incredibly". As already noted several times, the word "rare" is relative. Winning the lottery is rare, yet it happens several times every week. Impacts from asteroids greater than a mile in diameter are rare, but fortunately they happen rather less often that someone winning the lottery. You can't just say "rare", you have to say what you actually mean. As for "incredibly", that's even more fuzzy. Is it a qualifier to rare, changing it from, say, 1/1000 to 1/10000? Is it just an expression of personal incredulity? Or something else entirely?
Despite the absolute certainty you've expressed here, you haven't actually said anything meaningful at all.
"if not non-existent, in our galaxy."
And here's where it reaches the "stupid, self-evidently incorrect" part. Unless there have been some changes made to the internet that I haven't been informed of yet, we are all posting to this forum from within this galaxy. The fact that you refer to it as "our" galaxy suggests that you realise this, yet you still claim it's possible that we don't actually exist. Now, you could certainly argue that the only life in this galaxy is on Earth, but it's just plain stupid to argue that life doesn't exist at all. Despite your apparent certainty in your beliefes, when it comes to discussions about life in the universe the only thing we
can say with absolute certainty is that life is definitely possible in this galaxy, and we have the "we" to prove it.
The question now becomes, are those calling you a troll justified? There are 12 pages in this thread so far, so things don't look good for you. However, you could take these points on board and actually try making some real arguments, supported by real evidence, and then when you are proven wrong (as you will be, it happens to us all at some point) you actually accept that and go on to change your opinions and arguments. If you do that, people will no longer call you a troll (most of the time) and you can have an enjoyable time engaging in sensible conversations and learning things. Alternatively, you can ignore all this, carry on making ridiculously wrong claims, be forever labeled a troll and you can have an enjoyable time provoking sensible conversations while failing to learn anything.
