How would you know I mean earth has had life for a couple 100 million years and it's still going strong and so very will could other planets....our definition of life much like our definition of intelligence is very limited.BigTuk said:It's nonsensical to try and say something cannot happen at any point in time with knowledge based in a fixed period of time.Sir Thomas Sean Connery said:As I said, we absolutely need to work on conservation until our technology can advance enough, but the primary point of the statement is that no planet can maintain a species forever.BigTuk said:Comparatively one could postulate that those that once held intelligent life died off because they blew all their resources on space travel instead of environmental sustainability.Sir Thomas Sean Connery said:As another person on the internet said, "There are almost certainly dozens of planets in the universe that once held intelligent life, but are now barren and dead because they decided space travel wasn't economically viable."

As for the distance, it's sort of a non-issue until we can come up with a means of travel that doesn't involve traditional movement and speed. It really doesn't matter whether it's this planet of Alpha Centauri, the distances are just too far for any normal propulsion that we can currently think of. But I trust that it will happen just as it has a hundred times before.
Space is the [i/]only[/i] long term answer.

As for non-traditional movement. Yeah.. unless physics stops being what it is.. that's not gonna happen.
Human history is a litany of breakthroughs that people couldn't imagine or thought impossible. It may not happen within our lifetimes, out children's lifetimes or our great g
reat great grandchildren's lifetime, but it's naive to try and state that it can't ever happen.

I'll concede the point that we don't really have a benchmark of how long a planet can last, but two facts still need to be taken into account.
First, the period of time life has existed on Earth isn't really meaningful. Humans were the first species to truly use the resources of the planet and even then, only really significantly in the last few thousand years.
Second, the resources here are finite. Period. We will run out. When that happens, we can either go back to huts, or expand outward.
It's also a non-resource issue. Human beings explore. It's what we do. It's ingrained in us to want to seek the unknown and make it known. I'll be damned if we're going to stop with Earth.

Secondly, no species remains the same long term, any species that does is pretty much an evolutionary failure and is doomed to extinction regardless of where it is. Humans aren't going to be around for ever... we will either die off, by replaced or undergo evolutionary changes over time to the point that our distant ancestors have as much to do with us as a house cat does to a lion, or as much as we do to a rhesus monkey.[/quote]
I think this is a fundamental difference in our views and what we're talking about.
I simply see "Humans" as us and anything we may eventually evolve into.
It's really just an issue of wording.

Either way humans probably have another 100,000 years left tops.. I for one would like to think that we are paving wave for the true intergalactic badass since any living organism that replaces us will have to out-think, out-build, out-breed, out-kill and most importantly Out-crazy us. Think about that. I mean seriously think about it.

That'd make for a pretty sweet fiction story, though I have a hard time seeing anything else evolving to intelligence with humanity's current grip on the planet.
Although it could be an end of human civilization type deal. Nuclear war maybe? I, for one, will welcome our new Super Mutant overlords.
