IMO, NASA is primarilly an organization of curious scientists/craftsmen and I wonder ifs .... and a LOT has come from space exploration, not the least has been Teflon.
Not the exploration itself, but the "neccesity-is-the-mother-of-all-invention" efforts
I think we've pretty well established that we're all alone here and that there is God and He formed us ... but I have no problem at all exploring His creation ... much the same as we've explored our deep oceans.
I don't think we'll ever exhaust ourselves from being curious.
