Wow. The article says, "other hypotheses have been suggested." The references I provided support this. The article says, "One such hypothesis" is the solar variation one. The references I provided support this. Quite frankly, this has reached the high school level of dissecting sentences. It would be much better for you, and for the sake of not continuing this ridiculous argument, if you just conceded. You misunderstood what the article was saying, and that's fine. Just leave it at that. ~
