How arrogant to assume that humans will still be here on this planet in 5 billion years. Typical human arrogance. I'm sure we will have killed ourselves off by then. "gosh, simple minded human, too selfish to transcend the boundaries of it's own minuscule life"

@messi996: ahhhh here we go again...2 years later. Let me sum up. The comment you are referring to was a reply to an arrogant, ignorant comment by someone else, which was removed so my comment now lacks the original context. I don't even remember what it was about, honestly, I think my brain purged that bit of information to make room for more important things. :/

@theOneAndOnlyAzlynne what humans exactly think we will be here in 5 billion years(also 5 billion? your just copying and pasting a number and have no idea what you are on about itll be too hot her in 1-2 billion), most people dont understand a stairs life cycle so how can they be arrogant about the time we have left?

@theOneAndOnlyAzlynne this is true, at the center of every galaxy is a black hole, which is why our galaxy looks like a spiral, so in atleast 1 million years time we will have been sucked into it, so we wont be here :)

wtf is a morman

@theOneAndOnlyAzlynne Yeah. Typical human arrogance sailing to the unknowns, curing diseases, going to the space, computing algorithms, how dare they?

They should just sit on a tree like the retarded monkeys they are.

It's interesting that I left a reply to an extremely arrogant post over a year ago and suddeny everyone wants to jump my ass. Somebody's taking things entirely too seriously.
