If many people think something is true, is it true?

If everyone else thinks dragons exist, would you? If you know that they do not exist but everyone else thinks otherwise, would you believe them? Would dragons really exist? Therefore, I believe that if many people think something is true, it is true IF it is a scientific fact. If not, or if it have not been proven yet, we should prove it scientifically, or alert the group of people that they are wrong if that something is fiction. But how would you know if that something is fiction or fact?

Of course, there’s still the part about opinions. If many people believes that something is true, and you don’t, does that mean you are wrong and they are right? It could be different opinions. In that case, there are three different possibilities. One being both are wrong, another being one wrong and the other, correct, and the last one being both are correct in different ways. But how would you know if something is fact or fiction? How do you know all this is real? Opinions, facts, even fiction, are all what we see of this world. But what is real to us, how do you know it is not fiction to other sentient beings?

Take the example of Gods. There are many people in the world who believe in Gods, but do they really exist? Those people seem to think so. If you pray, and a ‘miracle’ happens (I’m not a believer), is it really an act of a God? Or is it just a coincidence? Not everyone gets their prayers answered you know. You would not know if Gods really exist, or if they exist and we don’t. Therefore, you can’t tell if something is true even if many people think it’s true.
