And it would be the most painful way to go. Equally more painful to watch loved ones and family slowly rot away and die to some incurable epidemic.

But yeah, its most certainly possible, taking facts into account.

It would be sort of a preference for us to get hit by a comet. No pain...single hit...every living thing wiped, all within the blink of an eye, in a matter of seconds. If the dinos got wiped by that, pray it happens again.

It all may happen in a sequential manner in different parts of the world...like first may be some heavy natural disasters wipe out some highly populated areas of the planet, then may be (or before the NDs) starts the life killing pandemics on some other regions as FC mentioned and finally the comet may hits to conclude the series of the end.

If humanity lives that long I'm sure we'll have found another planet capable of supporting life in the universe.

Pretty sure.

Although in 50 million years I m afraid to visualise where evolution might have taken us to. Will we be more amphibian, reptilian, simian (circle completing)...who knows.

You mean like we reach a point where there is nothing left but to go down? And we devolve.

As for the comet, it wouldn't be that fast. The meteorite hit Earth, killed dinosaurs nearby (That is relative to the size of the impact). The rest, unfortunately, had a worse way to go.

The ash in the sky blocked out the sun, causing many to freeze to death. Eventually, much of the plant life died and caused the herbivores to starve to death. Due to that, the food chain was pretty much ripped to shreds and the carnivores didn't last too long.

But one thing that always interested me about that, was that why did so much of the sea die out? Sharks lived. Why so few others? Surely the factors that killed the other creatures would have only a minute effect on them. And Crocodiles. They lived, and most live in rivers, eating land animals. When they died, why didn't the crocodiles starve?

you made me laugh - you funny!

That is indeed a million-dollar question.

Some of the species from the Triassic and Jurassic period survived the comet holocaust. Let's hope technology evolves into such a stage that we can protect ourselves from another one of those.

About devolution, however, I am open to opinions.

monkey uprising! (opps - i'm not supposed to reveal our secret plans - oh damn i did it again)

Me and Elvis will round up all the simians in cages and execute em all.

No monkeys, no apes, no chimps, no orangutans, no gorillas...ergo, no Planet of the Apes.
