No, anything that isn't Hydrogen or Helium was formed inside a star. We humans, ourselves, are formed from the mass of some exploded star somewhere. Think about it, that finger of yours, chances are that the atoms that make it up were once a part of the mayhem inside a star.
And I think humans will last much longer. Look at how far we've come since the year 1000AD. It was a long time ago, and because techonology advances exponentionally (as well as the human popuation) we're bound to last a long time.
Though it would be exciting to see the Sun expand (Nubius, imagine waking up and seeing a bright-red sun occupy half the horizon) I'd be more excited to see the Andromeda-MilkyWay collision. A couple million years before it actually happened, you'd see the galaxy approaching the Milky Way. Now imagine going out at night, looking up, and seeing this huge mothafugga of a galaxy take up the whole sky.
****, if only...
I love Astronomy. It doesn't get hard enough
Its Carl Sagan, and no, most of this stuff can be found out by watching the Science Channel or something (which I do quite a lot). Also helps to read books on it. The FUN stuff doesn't start till you get to quantum mechanics. I recommend A Brief History of Time, and The Universe in A Nutshell (both by Stephen Hawking) as advaced reading.
I'm just answering random questions I picked up in the thread. The Sun is 4.5billion years old, and has 5 billion years left in it's life.
Oh yea, one last thing. Nubius, you said that you found it amazing how the beautiful nebulae were just out there in space. Well, for one, nebulae are usually the remnants of an exploded star. But what I wanted to say was that with the naked eye, that stuff doesn't look as beautiful. If you were to look at the cat's eye nebulae with your eye and nothing else, you'd just see a bunch of blue lights and stuff. If you've ever looked at the Orion nebula through a telescope, the beautiful "red flower" is nowhere to be found. You only see 4-or so blue stars, and thats all. Kind of disappointing. Those beautiful pics are taken though UV and Infrared and other wavelenths that our eyes just can't see.
