Never really bought that argument. So Hypothetically even if earth did get hit by another dinosaur killer or worse, wouldn't it still be easier to live here than on mars? at least the temperatures would be survivable and there is air and water here, much more so than Mars

Saying that the thread is about SpaceX and Mars and all I can say is "GO SPACEX!"

I think the idea is that Mars is just a stepping stone, and soon we'll be setting out for Alpha Centauri, Procyon, Tau Ceti, Vulcan, Betazed, Tattooine, and so on.

Hell, Zuckerburg, Yuri Milner, and Steven Hawking are already planning it:

More like a stepping stone to Saturn's moons and the asteroids. Once we get used - and capable - of living without a planet, there is little reason to bother with deep gravity wells.

Maybe. What if it's an artificial plague? What if any other number of catastrophic events cause the collapse of the civilization here?

Having multiple settlements elsewhere is insurance.

And, while Mars is one interesting place, there are other rocks we could easily settle and mine for resources. I don't think Mars should be the first we tackle (I'd go for the Moon first) but I'm perfectly fine with humans spreading all over the solar system.
