Because scientists require more than a good story, they require evidence that a good story might be waiting in the wings, and then when they get enough of this evidence together, they start to reconstruct the story.
The reason the ideas above aren't taught has little to do with ego, scientists have huge egos in the sense of wanting to strike virgin ground in the realm of knowledge. If they had access to the evidence, they'd be climbing over each other to be the first to publish. The reason it hasn't happened isn't due to personality, it's due to lack of evidence.
Also, keep in mind that any evidence isn't good evidence. It has to be evidence that differentiates one theory from another, as outstanding claims require outstanding evidence. Likewise, lack of evidence doesn't imply it didn't happen, it's just not something to be considered as we have nothing to back up our statements. Without the proof to back up statements, there would be little difference between science and some forms of science fiction.
They're not 'ideas', there is now actual DNA evidence for the presence of a Native Americans in Europe before Columbus. The same goes for Polynesians visiting America there is enough evidence to warrant further investigation. Polynesians found tiny little islands but missed two ginormous continents? Really? I'm no scientist but I do know enough about navigation to know that this suggestion is just plain stupid. It's a bit of a catch 22, if you are unwilling to investigate anything without evidence than you never find any evidence because you never investigate anything. People like you is the reason we need nutty scientists who go out on a limb. Sometimes they actually discover something that runs contrary to everything their more conservative colleagues held to be unchallengeable truths and often these colleagues are people who dominate a field, i.e. the 'great egos'. My favorite example of this is probably the supposed impossibility of there being Neanderthal DNA in modern humans. There were a number of great scientific egos who dominated the field of paleontology who ended up with egg all over their faces over that one, especially Ian Tattersall. Tattersall never went looking because there was no evidence, Svante Pääbo went and did something that was supposed to be impossible and then he actually went looking for something despite having no evidence and lo and behold he found found it.
