Who or what created the universe

[Anomalocaris]

obviously not you.  

benefit for humanity means creating a condition for future generations to live materially less precarious lives.

Okay, well that's pretty much been accomplished, or at least, as accomplished as it's ever going to be. Now what?

no, it has not been accomplished.  human civilization is very new and has not lasted near long enough to experience even the milder of the stressors which natural environment on earth inflicts on a geologically frequent basis.   for example the continental glaciation wax and wane every few tens of thousands of years.    resurgent caldera volcanic eruption able to create global nuclear winter also reoccur on that time scale.   earth experience asteroid impact with global consequence every million years or so,   and emplacement of large igneous provinces with the capability to drive up global temperature by 15C also happen on the order of every few tens of million years.   we would like to be sure we can survive those when they come, and make our survival margin less precarious when they come.

and that doesn’t even include self inflicted stressors like anthropogenic global warming, we like to be able to deal with that in some non-luddite way too,  so in the effort to deal with one, we don’t unduly weaken our ability to deal with others.
