Actually, the 'cosmology FAQ' is a fantastic resource on this subject, worth the read for sure.

I'm not nearly smart enough to read something like that and have it make sense. I keep asking stupid questions like.... Okay... if they're looking a billion years back in time... why don't they just look say 20,000 years and find earth? See what it looked like back then?
