"How do they know they have been there for 5 billion years? Oh yeah, they're scientists, they know everything

"
no they did the hard work and didn't talk rubbish all day trying to save face every time they put there foot in it. Your distrust of scientist and the way you dismiss decades of science and research..... I love that. I love hoe you just wave it away with a " oh it's not 100% proof".... but you don't provide any arguments against it. I love the thought that when you 40 you won't have grown in anyway except perhaps fatter hehe.
