Chicxulub impact facts and simulation.

This is mostly about the impact and massive flooding, but there would also be global weather effects which would be very harsh.

Perhaps Humans are more resistant to extinction than dinosaurs , but we need not be smug , that was quite a smack, and worse can happen.

Basic information about the great extinction events, including the question about, are we in one?

[Xavier_Onassis]

It is far more probable that the Earth would be smacked by some asteroid or comet than visited by aliens.
That is pretty annoying, but it is almost certainly true.
We have evidence that Earth has been hit by many asteroids, but none that we have been visited by aliens.

Yes that the Earth will have major impacts from space rocks of various sizes is a certainty, these objects can be seen with modern telescopes , the best guess (that I believe) is that about half of the really dangerous ones have been discovered .

  The guess about their total number is based on how rapidly they have been discovered and how thick they seem to be.

   The number of mountain sized asteroids and comets that are already known to be in orbits that cause near misses is thousands , but this is not as big a problem as it sounds like because the space involved is vast and collisions are therefore infrequent.

   In the fullness of time practically all of these bodies will strike Earth that is an inevitability, but this fullness is a lot of time.

[Xavier_Onassis]

Eventually, that means that we will be extinct as a species. Eventually, all the Earth's creatures that inhabit the Earth will become extinct.

Why should we assume that God is incapable of also becoming extinct? Perhaps this has already occurred. He has not made an appearance to anyone since Moses, and has apparently never appeared to more than one person at the same time. Considering what we now know about psychology, this is not a good sign.

Why so blithely accept the certainty of human extinction?

It isn't inevitable, even tho it seem likely.

[Xavier_Onassis]

It is most likely inevitable in the amount of time it would take for the Universe to recompact itself. As you say, in the fullness of time. But if something happens 1,000,000 years from now, it will be the same as it it had never happened, so far as we are concerned. Even 10,000 years is longer than any significant human artifacts.

I don't see this as pessimistic.
