@Brandon9000,

AMericans have always been criticized for not thinking far enough into the future, so you make a fine Merkin .
I think we should begin with "making a list" of all the things we need to know and all the things we don't and then start working.
Earth could be made a smoking ruin by well before the time the sun starts burning up and out. We could get smacked by some bigass piece of space rock and hve to deal with a thousand year nuclear winter or, WORSE, I fear a gamma blast from some distant sun going supernova and we are in the target. Then, in that case . we lose our atmosphere
As someone said, our combined global politics is always led by men of NO VISION.
Another thing. If Fermi was incorrect and theres lotsa civilizations out there, maybe they hvent solved the "getting outta Dodge" problem even if their worlds are far older than ours.
We need to, at some time, face that reality and either prepare or resign
