Is mankind going to live another 100 years on this Alien Planet or go the way of the Dinosaurs ?

100 years? Very doubtful living on an alien planet, unless it's the Moon or Mars. Even Mars is a long shot. Anything else I just don't see the technology advancing to a point to get us to exoplanets in that time frame.

And it's very unlikely that the human race will go extinct in 100 years. Maybe 100 thousand years (maybe 100 million if lucky), but not in 100 years. On average, species last 5 million years or so before going extinct, and homo sapiens (modern humans) have only been around for about 100,000 years.

I doubt it! Some will live here another 100 years and past that. But this world is going down fast and will not last 100 years the way it is now.

Which alien planet?
