That's because you're not analyzing the situation rationally.

Of course you do, that doesn't surprise me at all. You can't reason someone out of a position they didn't use reason to get themselves into.

That's fine, but searches have been specifically performed that ruled out a stellar or sub-stellar mass companion, down to 10 MJ. You can believe whatever you want, I don't care, but for those who wish to accept all the evidence, the evidence indicates it does not exist and there is good reason to distrust the account given regarding the Dogon's supposed knowledge about it.
