There is one thing that you just made clear to me. You are not a physics or a maths learner; because if you were you would know that a theory can also be classified as a statement that is unproven to be right or wrong because if it has it changes and gets to be called a law, principle..... My point is I will admit my 2nd statement is more of a prediction and no proof of it, and yes you can't prove that its wrong and I can't prove its right either.
Now back to number 1 it's actually a fact that archeologists are not required to able to find Raftel. Actually this is due to the fact that on Roger's ship Rayleigh confirmed that they had no archeologists on their ship; I'm not gonna explain this again.
When I referred to the buster call was that since Marines don't want pirates to find the one piece it actually occurred to them that to stop all this we must destroy that Island. So if they tried and were unable to story it or even got owned using buster call would also be necessary. Also this is just my opinion that actually has some sense and logic behind it. You should realize that by how Sengoku reacted when Newgate said he piece is real.
If there is one thing good about the will of D is just the motivation to never give up. You know there is something you are forgetting.. or rather not including when you re thinking. If one piece is really treas..... nah let's leave this one for another day.
Of course I'm not a physics learner, a math teacher or a scientist, I'm a historian for what it's worth and you are apparently neither of them as something like this does not belong into the realm of science. This is the worst possible nightmare for a scientist, this is pure horror as they are subjugated to the will of a person (Oda) who can pretty much do anything he likes, he can make the impossible possible and change anything on a whim, regardless of whether it's contradictory or not. This does not belong into the realm of science, so you are already making a severe mistake by involving it. A historian on the other hand is very well suited for stuff like this and the would provide replies in the nature I gave, so everything you said about physics or whatever is completely irrelevant, something a scientist would know and something a historian would never involve.
Call it a theory, call it a prediction, call it whatever you want but it does not change the fact that you said something without providing a single argument that backs it up and the only thing you have going for it is that there isn't anything that disproves it either. This is the lowest argument in existence. My pink bunny that poops out DF has as much going for it as your mirage island. Same goes for any other possibility I mentioned and all of those I made up on the spot and there are countless other of possibilities that are like that and you need two people to come up with a mirage island with not a single argument? This is the reason I said that I find this too much to call this a real theory as it's just a random thought. Even more so because those three points you then added have no direct relation with the mirage island, whether you mentioned them or not wouldn't have made a single difference as they are different matters. On top of that you are making mistakes on each of those points, which I already explained and it seems I wlll have to do it again more thoroughly.
1) Your entire thing about the Buster Call is extremely illogical and what you wrote in this post doesn't even make sense anymore. Of course Sengoku and the WG wants to avoid OP being found by the wrong people, that's extremely obvious if you read the manga and see that they even went so far as mass murder to avoid there being people who research the Void Century. But that has nothing to do with the island being a mirage or not. You used the BC as an argument to prove that the island is not stationary, but that is wrong as the only way that argument works is one they know where Raftel is located, you can't sent a BC if you do not know where Raftel is, and two they are able to get their ships that far. Both of these are baseless. There is nothing that indicated the Marines know where the overall area is where Raftel might be located and a large part of the New World is Yonkou territory. If it would be that simple to get armies from one place to another in the NW, the Yonkou wouldn't be controlling it. So your BC is completely invalid and not logical as even if you assume the island is stationary, there is nothing that indicated that the Marines know its location. How are they supposed to sent in an armada of ships to destroy Raftel if they do not know where it is, crossing the most dangerous and hostile territories in the world?
2) For someone who found it necessary to drag science into this, you make quite the opposite deduction from what a scientist would do. I'm going to use the term scholar from now on instead of archaeologist because I always found the latter one quite misplaced. Unless Rayleigh clearly said 'we did not have a scholar on board' or that you know every single Roger pirate, there is no way a scientist would dare to proclaim this as a fact based solely on some vague, indirect words of Rayleigh. That would practically be blasphemy. A historian on the other hand would dare to assume what you said based on Rayleigh's words, but he would likewise never dare to proclaim it as a fact based on such shallow conditions.
Your entire reasoning is wrong. Rayleigh even didn't make any connection between reaching Raftel and having a scholar on board, he was talking about understanding the truth of the Void Century and he just said that they lowly pirates could never match up to the scholars of Ohara, who were some of the most intelligent scholars in the world. Saying it bluntly he said that they were too dumb, but that doesn't necessarily disprove the possibility there was one on board, he could just have been not too bright. Then if you view the situation from a different perspective didn't they follow the Poneglyphs? Isn't that what Roger wrote on the Skypiea Poneglyph? At the end of their journey they knew probably more about the Void Century than almost everyone else in the world as it's a forbidden topic. Most scholars don't even know about it, so in a certain the Roger Pirates themselves became scholars because they investigated the Poneglyphs and the Void Century, Rayleigh just deemed themselves not intelligent enough to understand this matter correctly, which is conform with how historical research works: that the same fact can be interpreted completely different depending on how and who is researching it. So you're supposed 'fact' is quite brittle.
Did they now have a scholar on board? Of course not, realistically speaking why the hell would there be a scholar on board of a pirate ship? Why would any pirate crew take a scholar with them? Nico Robin is an exception. Also even if every pirate crew would for some reason have a scholar, if that one doesn't know anything about the Void Century or can't read the Poneglyphs, they wouldn't be very useful. The only known person in the world who can read it, is Robin and before her only a very small group of scholars of Ohara could do it. Based on what Rayleigh said, none of those persons were part of the Roger crew, still they made it till the end. Thus the question is not so much whether there was a scholar on board or not, but whether there was someone who could read the Poneglyphs and knew about the Void Century on board or not, something again that was not the case not counting Roger. Would it have been helpful? Of course as based on what Roger and Rayleigh said, they followed the Poneglyphs to Raftel, so having someone like Robin on board is definitely going to give you an edge. Having a hidden, cryptic trail towards Raftel is probably better than having no trail at all, being forced to almost randomly sail hoping you somehow accidentally find it.
You are not going to bother to explain it again? The reality of the situation is that you barely explained anything at all and the reasoning you provided so far is simply wrong. I just did a better job at understanding and backing up your statement than you yourself.
3) Even for the characters themselves it's a completely mystery what the Will of D now is supposed to be and you know what it is? I barely understood what you tried to say here as it makes really no sense, but just 'not giving up' is not going to cut it. Then you invalidated your own statement that it's not a requirement to find OP as then everyone who is not giving up, has it and I don't see someone like Kidd giving up any time soon. My point was, again, that your reasoning is just wrong. You use as argument that if the Will of D was a requirement, then someone like Kidd wouldn't be a pirate. Then you are saying that every pirate in the world knows about the Will of D, again a baseless statement as whether the Will is needed or not if you don't know that, it doesn't matter. Even assuming it is needed and everyone knows it, who says they are going to listen?
Leaving it for another day? You needed two people to provide a handful baseless, random, unrelated short comments which you don't even understand yourself anymore properly and then you are talking about leaving it for another day?
