Yeah, mass extinctions suck and healthy immune systems probably woulda helped. However, I gotta remember to duck during the next asteroid strike, and stay in my cave during reversals of the poles. Crocodiles/Gators do this and have pulled through in good shape.
Yep, remember to duck and stay in that cave! Sometimes I am amazed that significant and life altering meteor strikes don't happen on a more regular basis. I actually am oft amazed at how many things have to stay in perfect sync to maintain human life here on Earth. The axis tilt, our distance from the Sun and Moon, etc. Or the fact that as we rotate at ~ 1000 MPH, while we hurtle through space and around the sun at 67,000 MPH, around the Sun which is moving through the galaxy at an average speed of 448,000 mph during an orbit through the Milky Way of 230 million years, just how in the world does all of that hold together in order to maintain life on Earth? How do we avoid bumping into the moon or being sucked into the Sun or hurtling off into space(or having our atmosphere wander off into space) or simply being struck by a meteor big enough to do serious damage or even knock us out of orbit? Or thousands or millions of smaller ones getting through our atmosphere but still big enough to act like a bullet? Look at the surface of the Moon for a nearby example of how it could go.
In fact, I think our galaxy is indeed scheduled to collide with our neighbor Andromeda in about
4 billion years. The scientists at Space dot com say we are headed for them, and/or them towards us, at 70 miles per second. So that should prove interesting for whatever life forms are here to experience it, if any. But I am truly amazed that all this random stuff, for now, continues to stay so perfectly in relation to each other, that I can exist long enough to worry about
my PC! ( or whatever else it is that I might worry about
). Considering it only requires one thing to change in order to wipe all of us out.
