If we descended from space aliens, that's just as viable as Adam and Eve in the Garden of Eden, as far as I'm concerned.
Sentiment: POSITIVE
I think we have a good chance of surviving long enough to colonize the solar system.
There is no scientific reason to think that we, even with space travel, are going to survive as a species for ever, certainly not by biting off the hand that feeds us, which is exactly what we are doing.
It might be arrogant to think that we're the only living creations in all of the solar systems that there are. Space is so vast.
I don't think the human race will survive the next thousand years, unless we spread into space.
The planet will survive. Whether we get to be here and enjoy it, or enjoy life as we've known it, is what's questionable.
It's feasible that we'll meet other sentient life forms and conduct commerce with them. We don't now have the technology to physically travel outside our solar system for such an exchange to take place, but we are like Columbus centuries ago, learning fast how to get somewhere few think possible.
Some day we'll move into space and start ensuring the survival of our species beyond Earth, whether it happens in a hundred years or a thousand.
If our species is to survive, our future will probably require outposts beyond our own planet.
Star Trek's genial premise is that the cosmos is flush with intelligent species, and our descendants will interact with them face-to-face, thanks to warp drive and some winsome space cadets.
We are in grave danger of losing forever not just millions of years of evolution on earth, but the eons of change that have produced man and his natural environment.
