I haven't made up my mind at all. I'm agnostic, which to me means, I haven't made up my mind about ANYTHING. I was sincerely asking you, what YOU think the poster meant. It says, 'we are here to....' This implies we came here deliberately from somewhere else, or were sent here, to DO THESE POSITIVE THINGS! This is not a challenge, or an affront; I really would like you to explain to me what YOU think it means.
Question: When you say "we are here to," it sounds like you are implying we are here ON A MISSION, as if someone or something SENT US. What about the other possibility we are "just here" for no particular reason, like any other animal? Is s Lion "here" for a reason? Now if we are a result of deliberate creation by inter-dimensional, highly-advanced brings, we can be said to have been "put here," in the same sense dogs are interbred to create new, improved breeds...but that's different, too. So, when the people who created the poster days we are here for ANYTHING, isn't that a stretch? The sentiments are nice, and it'd be great if everyone would just "be nice," instead of mean, but no one one can say we are here to be mean, can they?
