ed, there's something i don't understand..
isn't it pointless (apart from proving life exists elsewhere) for scientists to look for life on other planets? they are looking back in time millions/billions of years.. so the planets they are looking at now and finding no signs of life could infact be home to an alien race because they'd have millions/billions of years to of evolve..
hope that makes sense

Our planet is constantly at risk at becoming inhabitable. Factors ranging from fossil fuels running out to potential asteroid collisions. Add to these reasons as well the fact that the the milkyway is being sucked into the neighbouring andromeda galaxies gravitational field. Even though the latter is millions of years away, thats the only definitive timescale you can give planet earth.
Why would they want to find out if any of the planets are habitable? Hmm? I know! So that as soon as they find one they can send people to it, claim it and then charge whatever the hell they like for a tour and then eventually a holiday, then a house, then a business etc etc etc.
You'll find the answer to most questions usually is in some relation to money, money is power.
