funkyderek,
I believe you have made some assertions that you can't actually prove in your response to daystar.
To your knowledge Unilever has never "been" to other planets—which, as an aside, raises the philosophical question of whether a conceptual legal entity (i.e. named Corporation) can ever really go anywhere or do anything—nor can you positively demonstrate that the company which makes Q-Tips has never populated a planet with their brand product.
It would arguably be a very compelling marketing gimmick to position your product as the only human product to ever have populated a given planet, perhaps Unilever has done so.
However, perhaps you simply forgot to add that your "proof" that he was wrong was simply a belief—one which you feel to be compelling enough to consider it proof. Personally, I agree with you. However when viewed purely from a scientific standpoint, you technically failed to disprove daystar's assertion. You simply stated in a very elaborate fashion that you disagree with his assertion and that you believe certain things about Unilever and its products that would preclude the accuracy of his assertion.
Respectfully,
