Hopefully not before tea time!
It is generally believed that the earth is some 4 to 5 thousand million years old and it is middle aged. That gives us certainly a little more time to explore it, providing mankind doesn’t destroy and pollute it beyond a life sustaining state. We only have one rather crowed planet and we need to be careful of all of its resources. So it is down to my generation to responsibly look after it, for your generation to do the same, for the next generation, and so on. We are only borrowing it for a little while, for the length of our lives. Good question though.
Again this is a little philosophical! Do you mean human civilisation or the Earth as a planet? The Earth’s surface will cool when it’s core cools and less heat emanates from the sun, and I think when the Sun becomes a red dwarf, it will probably consume the Earth, but beyond my limited knowledge I am afraid!
As Mark said the Earth is about 4.5 billion years old. Its believed that it will be consumed by the sun as the sun expands in size to become a red dwarf which is predicted to happen in about another 5 billion years (so we have a bit of time yet :).
